State what criteria are used in viral classification. Like plant cells, some euglenoids are … The flagella can be acronematic (Fig. The first group is macro algae, which includes green, brown and red algae. Classification of Kingdom Plantae. Membrane bound cell organelle like chloroplast, mitochondria and ER are absent. Chrysophyceae 4. • Too much growth of green algae can indicate pollution from: excess nutrients • This is a condition know as: eutrophication • It often occurs where: rivers meet the coast • The excess algae can cause "dead zones" because when the algae dies decaying bacteria use: oxygen Protozoa Definition. In Xanthophyceae flagella are two, unequal apical one acronematic and one pantonematic i.e., heterokontic. There is three main Algae classification: Chlorophyceae – These are called green algae, due to the presence of pigments chlorophyll a and b. Its subgroups are the diplomonads, parabasalids, and euglenozoans. Algae are the simplest multicellular plants. The presence or absence of pigments which impart colour to the algae forms the main basis of classification of algae. Spiral shape in. The second group is microalgae as phytoplankton in the coasts, lakes and oceans, which in‐ cludes diatoms, dynoflagellates, green and brownish flagellate, and blue-green algae. Guest. In this article we will discuss about the Fritsch’s and Smith’s classification of algae. In Phaeophyceae the reserve food material is laminarin or mannitol. One of the best known algal classification was proposed by Fritsch who divided them into 11 classes (1945). Most forms of algae are aquatic so they are living in fresh water and in sea water too. On the basis of nuclear organization algae can be prokaryotic or eukaryotic. Microorganisms are very diverse. Xanthophyceae 3. protozoa, algae, and fungi •1937Prokaryoteintroduced for cells "without a nucleus" •1961Prokaryote= cells in which nucleoplasm is not surrounded by a nuclear membrane • 1959 Kingdom Fungi • 1968 Kingdom Prokaryotae proposed • 1978 Two types of prokaryotic cells found Timeline 2. Classifications of algae as Proposed by some workers are: F.E. This division has all unicellular flagellates. Fritsch (1935, 1945) in his book “The Structure and Reproduction of the Algae” proposed a system of classification of algae. Nuclear Organization 2. Share Your PPT File. Algae - Algae - Photosynthesis and light-absorbing pigments: Photosynthesis is the process by which light energy is converted to chemical energy whereby carbon dioxide and water are converted into organic molecules. Fritsch’s Classification: The algae have broadly been divided by F. F. Fritsch in 1935 into eleven classes according to their colour: i. Chlorophyceae or green algae, e.g. Common examples are Volvox, Fucus, Spirogyra, Chara, Polysiphonia, Ulothrix, etc. The flagella have 9 + 2 pattern of component fibrils. The pigments in algae can be chlorophylls, carotenoids and biloproteins. Type of Life Cycle and Reproduction: The best answers are voted up and rise to the top. The nature of reserve food can be a criterion for distinction of different groups of algae. 0. Hence came the five kingdom classification. Kingdom: Fungi. He treated algae giving rank of division and divided it into 11 classes. Nature of Cell Wall Components: Type # 3. Some of the types are: 1. A plant kingdom is further classified into subgroups. Algae are photosynthetic eukaryotic organisms. Disclaimer Copyright, Share Your Knowledge What are the general characters of bryophytes? E.g. Classification of Algae: Class. Botany, Class 11 Learning Objectives. Regarding the naming of enzymes involved in the replication of viral nucleic acid, state what the "dependent" part of the name refers to and what the "polymerase" part of the name refers to. Bryophyta Some marine brown and red algae produce large amounts of hydrocolloids. It is the largest class of algae; They are commonly known as green Algae. Eleven classes proposed by Fritsch are as follows: 1. Cyanophyceae or blue green algae are prokaryotic in nature whereas all other classes of algae are eukaryotic. Content Guidelines 2. Different groups of algae have different types of pigments and organization of thylakoids in chloroplast. Scientists have been trying to classify living organisms in various ways for centuries. Properties and Classification of Microorganisms Since the cell is the basic unit of all living things, you might think it is a simple structure. The kingdom-Plantae has been described under algae, bryophytes, pteridophytes, gymnosperms and angiosperms. Many scientists have spent their … Explore More: Thallophytes. Cell division by mitosis and meiosis is not found. Classification is based on pigments, flagella and reserve food material. Vote Up 0 Vote Down Reply. His classification of algae is mainly based upon characters of pigments, flagella and reserve food material. DNA fibrils are free in nucleoplasm and are not associated with histones. 4. Euglenophyta.

Class 2: Sarcodina. The first group is macro algae, which includes green, brown and red algae. ϒ Carotene and lycopene are found in Chlorophyceae. The algae belong to the subphylum Thallophyta of the kingdom Protista in modern classification of organisms. The chlorophylls in algae are chlorophyll a, b, c, d and e types. Some of the motile and non-motile algae may form a colony known as Coenonbium. … Micro-algae have the capacity to reduce atmospheric CO2 levels, thus fixing the increasing percentage of CO2 in the atmosphere, responsible for the global pollution problem. Types of Classification System These includes artificial system, natural system and phylogenetic system of … In prokaryotic e.g., Cyanophyceae—nucleus is not organized as nuclear membrane is absent. Chlorophyceae (Green algae) General characterstics of Chlorophyceae. Some species shows Alternation of generations in their life cycle. The chromatophores of different classes of algae differ in number of thylakoids per granum. e Carotene is present in Bacillariophyceae. Algae are usually green, but they can be found in a variety of different colours. Some acellular organisms like viruses and viroids as well as the lichens are not included in the five kingdom system of classification. Concepts of Botany Algae (PDF 21P) This note contains explanation of algae, structure of alage and its classification. • Green algae can be unicellular, colonial and multicellular. Root, Stem and Leaves. Photosynthetic pigments: They possesses chlorophyll a, chlorophyll b and small amount of β-carotenoids. Some are unicellular eg. Nature of Reserve Food: The primary product of photosynthesis i.e., starch is same in all groups of … Xanthophyceae or yellow—green algae e.g. Some of the characteristics are: Classification of Phylum Protozoa. What is the significance of the Hardy-Weinberg equilibrium? Latin ‘alga’ means seaweed. The process occurs in almost all algae, and in fact much of what is known about photosynthesis was first discovered by studying the green alga Chlorella. Chlorophyceae 2. Essay on Harmful Aspects of Algae | Biology. tonematic flagella, (C). These are eukaryotic organisms, autotrophic in […] But biologists wanted a broader system of classifying living organisms. Porpyra, Laminaria and Sargassum. Answer Now and help others. In Xanthophyceae pectic substance is more common. Nature of Reserve Food. In Xanthophyceae oil and leucosine are reserve food materials. Type # 2. Blue. (Fig. In Rhodophyceae rhodophycean or floridean starch and in Cyanophyceae myxophycean starches are the reserve foods. In Cyanophyceae the thylakoids are free in cytoplasm as chloroplasts are not found and pyrenoids are also absent. Many of the protist species classified into the supergroup Excavata are asymmetrical, single-celled organisms with a feeding groove “excavated” from one side. Kingsley Emoka. About 70 species of marine algae are used as food, e.g. (adsbygoogle = window.adsbygoogle || []).push({}); On the basis of photosynthetic pigments algae classified into three classes. This supergroup includes heterotrophic predators, photosynthetic species, and parasites. Euglena are fresh and salt water protists. The type, number and position of flagella are important basis for separation of different classes of algae. Cryophilic algae occur in snow and ice (see red snow); thermophilic algae live in hot springs; edaphic algae live on or in soil; epizoic algae grow on animals, such as turtles and sloths; epiphytic algae grow on fungi, land plants, or other algae; corticolous algae grow on the bark of trees; epilithic algae live on rocks; endolithic algae live in porous rocks or coral; and chasmolithic algae grow in rock fissures. The overview of this classification is demonstrated here in the flowchart. Colour. Algae possess the usual eukaryotic structures - Golgi apparatus, mitochondria, … Flowchart 2 : Classification of Monera Protista Nutrition Autotrophic or heterotrophic Cell wall Composed of chitin Locomotion Reproduction By Appendage like cilia or flagella Sexual or asexual Examples Eukaryotic unicellular organisms such as protozoans, unicellular algae and diatoms Flowchart 3 : Classification of Protista. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. This article throws light upon the top six types of Classification of Algae. Where are the pollen grains formed in the flower? There are four distinct groups within the algae − Group 1 Prokaryotic algae include two divisions: Cyanobacteria and Prochlorophyta.. − Group 2 Eukaryotic algae with chloroplasts surrounded only by the two membranes of the chloroplast envelope and includes mainly two … it is a traditional system as well as a phylogenetic system of classification of plants. The heterotrophic eukaryotic, multicellular organisms lacking a cell wall are included in the Kingdom Animalia. Haplontic life cycle, diplontic life cycle and triphasic life cycles are characteristic of different groups. In Chlorophyceae flagella are 2 (Fig. The heterotrophic eukaryotic, multicellular organisms lacking a cell wall are included in the Kingdom Animalia. Algae - Algae - Classification of algae: The classification of algae into taxonomic groups is based upon the same rules that are used for the classification of land plants, but the organization of groups of algae above the order level has changed substantially since 1960. Criterion for classification: Proposed by R.H Whittaker (1969) a) Complexity of cell structure: prokaryotic and Eukaryotic . In Prasinophyceae, prasionate type flagella are found. 200 species are included in this category. Chlorophyll c is found in Phaeophyceae and Cryptophyceae. 1. Single-celled microorganisms were the first forms of life to develop on earth, approximately 3 billion–4 billion years ago. In Rhodophyceae the cell wall is made of non-cellulosic polysaccharides like xylans and galactans. In Rhodophyceae thylakoids are single and widely separated in chromatophores and pyrenoids are naked. The contents of this documents are Dichotomous Key to Freshwater Algae, Groups of Cyanobacteria & Algae, Dinoflagellates, Euglenoids, Brown, Golden brown, and Yellow brown Algae … Asexual: asexual spores (motile zoospores). 9 months ago. Taxonomic classification of algae is based upon the same rules that are used for the classification of land plants. The Gram stain characterizes bacteria based on the structural characteristics of their cell walls. Sexual: isogamous or oogamous type gametic fusion. The thylakoids are arranged in stacks in granum of the chloroplasts. In Chlorophyceae the reproduction can be isogamous, anisogamous and oogamous, the life cycle can be simple or complex. What are the three classification of algae under morphological and physiological difference. In Chlorophyceae the reserve food is starch. In all other classes the basic flagellar structure is similar. (according to the latest classification system) P. graminis is an obligate parasite, and heteroecious rust. In fact, even Aristotle classified living organisms on the basis whether they lived on land, water or air. In Phaeophyceae cell wall contains alginic acid and fucinic acid. Classification of Plant Groups- Cryptogamae and Phanerogamae In 1883, A.W. Name the types of nitrogenous bases present in the RNA. TOS4. The second group is microalgae as phytoplankton in the coasts, lakes and oceans, which in‐ cludes diatoms, dynoflagellates, green and brownish flagellate, and blue-green algae [21]. The chloroplasts shows various shape ie. 1. Nothing could be further from the truth. The use of algae in integrated aquaculture has also been recently reviewed by Turan (2009). Eichler gave a system of classification for the whole plant kingdom. 1. classification based on pigmentation 2. classification based on cell wall 3. classification based on nature of flagellum 4. classification based on food resevoir. Pigments Present. Phylum: Basidiomycota. Before sharing your knowledge on this site, please read the following pages: 1. Share Your Word File Class 3: Sporozoa. This classification was carried out in 1986 and placed spirochetes, spiral and curved, aerobic bacteria and facultatively aerobic rods, obligate anaerobic bacteria, aerobic and anaerobic cocci, sulfate and sulfur-reducing, rickettsias, clamydias, and mycoplasmas in this group. Order: Pucciniales. The cell is complex in its makeup and its function. protozoa, algae, and fungi •1937Prokaryoteintroduced for cells "without a nucleus" •1961Prokaryote= cells in which nucleoplasm is not surrounded by a nuclear membrane • 1959 Kingdom Fungi • 1968 Kingdom Prokaryotae proposed • 1978 Two types of prokaryotic cells found Timeline Green. In Chlorophyceae there are 2-6 thylakoids per granum and the pyrenoids are covered with starch plates. There are unicellular algae as well as muticellular filamentous algae. 1.A-D). The primary product of photosynthesis i.e., starch is same in all groups of algae but due to accumulation of food over long period the nature of insoluble reserve food may be different. These are common only in Rhodophyceae and Cyanophyceae. What is a mushroom shaped gland? 2B) or whiplash, pleuronematic or tinsel and prasionate in type. Algae, bryophytes, pteridophytes, gymnosperms and angiosperms are included in this group. In Rhodophyceae, R-phycoerythrin is the chief pigment and in Cyanophyceae, C-phycocyanin is the chief pigment. Thus, they are among the large producers on the earth; especially in aquatic habitat. The biloproteins are water soluble pigments and can be phycocyanin, phycoerythrin and allophycocyanin. For example, sexual reproduction is completely absent in Cyanophyceae. Classification of Algae. Eleven classes proposed by Fritsch are as follows: Welcome to BiologyDiscussion! For instance, algae living in snow contain carotenoid pigments in addition to chlorophyll, hence giving the surrounding snow a distinctive red hue. Classification of algae 1. Examples are Chlamydomonas, Spirogyra, and Chara Phaeophyceae – Also called as brown algae, they are predominantly marine. Algae, bryophytes, pteridophytes, gymnosperms and angiosperms are included in this group. Chlamydomonas, Volvox, Oedogonium, Spirogyra, Vaucheria, Chara, etc. In Cyanophyceae and Rhodophyceae flagella are completely absent in vegetative and reproductive structures. Economic Importance of Algae: Almost 50% of carbon fixation on earth is carried out by algae. The inner layer of cell wall in algae is generally made up of cellulose, which is insoluble polysaccharide and the outer layer is made of pectic substances. Table of Contents hide. In Chrysophyceae cell wall is non-cellulosic which is silicified or calcified. Family: Pucciniaceae. Cyanophyceae (Blue Algae) Phycocyanin. Chlorophyll b is primary pigment of Chlorophyceae and Euglenineae. The cell wall in Chlorophyceae is made up of cellulose. Examples include green algae, red algae and brown algae. Sub Phylum B: Plasmodroma. ... Kingdom Plantae (Algae, Bryophytes, ferns, gymnosperms, Multicelled eukaryotes) Cell structure: cellulosic cell wall, presence of plastids . The pigment is one of the most important criteria used in differentiation of classes in algae, as algae were initially and primarily separated on the basis of colour e.g., green algae, red algae, brown algae or blue-green algae. Thallophyta includes plants with primitive and simple body structure. In Phaeophyceae flagella are two lateral, one acronematic and one pantonematic and unequal in size. flagellum. Photosynthetic organisms (plants, algae, cyanobacteria) are considered photoautotrophs- utilizes light as energy source and CO2 as carbon source Ability to oxidize H2O and release molecular oxygen, a lithotrophic activity Organism whose activities are phototrophic, autotrophic, and lithotrophic, and the classic "photosynthetic equation) Some acellular organisms like viruses and viroids as well as the lichens are not included in the five kingdom system of classification. You could easily see the previous 2 types of main living beings, but not these microorganisms, because they can’t be observed with your naked eye. In some cases lipids and proteins are also present in them. They are commonly found in aquatic environments including freshwater, marine and brackish water. Nature of Cell Wall Components 3. Share Your PDF File The presence or absence of sexual reproduction, complexity of reproductive organs, method of sexual reproduction i.e., isogamy, anisogamy and oogamy are important criteria of classification in algae. As the group implies, microorganisms are These pigments are present in sac like structures called thylakoids. Algae exist in environments ranging from oceans, rivers, and lakes to ponds, brackish waters, and even snow. Algae also cannot be seen with the naked eyes. In Xanthophyceae, Phaeophyceae and Bacillariophyceae there are 3 thylakoids per granum and pyrenoids are without starch plates. (With Methods)| Industrial Microbiology, How is Cheese Made Step by Step: Principles, Production and Process, Enzyme Production and Purification: Extraction & Separation Methods | Industrial Microbiology, Fermentation of Olives: Process, Control, Problems, Abnormalities and Developments. 3. In Cyanophyceae or blue green algae the cell wall is more like bacteria and is made up of mucopeptides. Flowchart 2 : Classification of Monera Protista Nutrition Autotrophic or heterotrophic Cell wall Composed of chitin Locomotion Reproduction By Appendage like cilia or flagella Sexual or asexual Examples Eukaryotic unicellular organisms such as protozoans, unicellular algae and diatoms Flowchart 3 : Classification of Protista. They are either motile or non-motile. Chlorophyll a is present in all classes of algae. Botryococcus braunii is a green, pyramid-shaped planktonic microalga that is of potentially great importance in the field of biotechnology.Colonies held together by a lipid biofilm matrix can be found in temperate or tropical oligotrophic lakes and estuaries, and will bloom when in the presence of elevated levels of dissolved inorganic phosphorus. Chlorophyll e is confined to Tribonema of Xanthophyceae. May 10, 2017 This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. Genus: Puccinia. They include bacteria, fungi, algae, and protozoa; microscopic plants, and animals. Chlorophyceae (Blue Green Algae) Chlorophyll-a and b. 2A), 4 or indefinite in number, apical or sub-apical in position and acronematic type i.e., isokontic. The classification of algae can be done in many ways since there is a millions of kind. The carotenoids are of two kinds: Carotenes and Xanthophyll’s. The plant body is thallus, they may be filamentous, colonial, branched or unbranched. Our mission is to provide an online platform to help students to share notes in Biology.

The reproduction is oogamous and life cycles are usually complex in Rhodophyceae and Phaeophyceae. Kingdom Plantae includes algae, bryophytes, pteridophytes, gymnosperms, and angiosperms. Pigmentation and Photosynthetic Apparatus: Type # 6. Hierarchies of Life Protista due to the fact that the kingdom is so diverse, and there was a mixture of results for specific species. What is the significance of transpiration? Which organelle is known as “power house” of the cell? The first level of classification among plants depends on whether the plant body has well-differentiated, distinct components. Class: Pucciniomycetes. There are about 20 types of xanthophyll’s commonly found in algae e.g., Neoxanthin, neo-fucoxanthin, fucoxanthin, chaetoxanthin, siphonoxanthin, oscillatoxanthin. Chlorophyceae (green algae) Phaeophyceae (brown algae) Rhodophyceae (red algae). The cell wall in algae is generally made up of polysaccharides. Among the carotenoids, β carotene is found in all classes of algae. Privacy Policy3. 1. […] 1.1 ClASSIFICAtIon The classification of algae is complex and somewhat controversial, especially concerning the blue-green algae (Cyanobacteria), which are sometimes known as blue-green What is its function? ii. 11. Levels of Classification of Plants: There are three levels of classification among plants. As these xanthophyll’s are restricted to certain classes, the xanthophyll’s are important diagnostic characteristics of algae. Classification is based on the following criteria: Plant body: Presence or absence of a well-differentiated plant body. These are pantonematic and covered by minute hairs. Algae are the green slimy blanket which covers the rock surface or the top of the ponds or a poorly kept aquarium that have the ability to conduct photosynthesis. Eukaryotic algae have well differentiated nucleus, mitochondria, chloroplast and endoplasmic reticulum in their cell structure. Cryptophyta. 5 Stages in Life cycle of Puccinia. classification of algae 5. They produce their own food by photosynthesis, hence they can be known as Autotrophic. If you have snorkeled or gone scuba diving off the California cost you may have come across bull kelp, a type of brown algae that belong to the Protist kingdom.
