There are unicellular algae as well as muticellular filamentous algae. 11. Protozoa Definition. As these xanthophyll’s are restricted to certain classes, the xanthophyll’s are important diagnostic characteristics of algae. In this article we will discuss about the Fritsch’s and Smith’s classification of algae. 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 In Cyanophyceae the thylakoids are free in cytoplasm as chloroplasts are not found and pyrenoids are also absent. In Chrysophyceae cell wall is non-cellulosic which is silicified or calcified. Euglena are fresh and salt water protists. 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. It is the largest class of algae; They are commonly known as green Algae. 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. The presence or absence of pigments which impart colour to the algae forms the main basis of classification of algae. The carotenoids are of two kinds: Carotenes and Xanthophyll’s. What is its function? Hence came the five kingdom classification. The chloroplasts shows various shape ie. The nature of reserve food can be a criterion for distinction of different groups of algae. 1. (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. Answer Now and help others. Bryophyta In Rhodophyceae rhodophycean or floridean starch and in Cyanophyceae myxophycean starches are the reserve foods. 0. 2B) or whiplash, pleuronematic or tinsel and prasionate in type. Eichler gave a system of classification for the whole plant kingdom. Taxonomic classification of algae is based upon the same rules that are used for the classification of land plants. 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. Economic Importance of Algae: Almost 50% of carbon fixation on earth is carried out by algae. 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 first group is macro algae, which includes green, brown and red algae. Gaurab Karki Class 1: Mastigophora. 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 Sub Phylum A: Plasmodroma. 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 Pigments Present. Class 3: Sporozoa. Microorganisms are very diverse. Asexual: asexual spores (motile zoospores). Nature of Cell Wall Components 3. Criterion for classification: Proposed by R.H Whittaker (1969) a) Complexity of cell structure: prokaryotic and Eukaryotic . 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. Thallophyta includes plants with primitive and simple body structure. Spiral shape in. In Chlorophyceae the reserve food is starch. 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.

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. Guest. The first level of classification among plants depends on whether the plant body has well-differentiated, distinct components. Cryptophyta. Table of Contents hide. Some acellular organisms like viruses and viroids as well as the lichens are not included in the five kingdom system of classification. Sexual: isogamous or oogamous type gametic fusion. The heterotrophic eukaryotic, multicellular organisms lacking a cell wall are included in the Kingdom Animalia. Like plant cells, some euglenoids are … What are the three classification of algae under morphological and physiological difference. In prokaryotic e.g., Cyanophyceae—nucleus is not organized as nuclear membrane is absent. His classification of algae is mainly based upon characters of pigments, flagella and reserve food material. Haplontic life cycle, diplontic life cycle and triphasic life cycles are characteristic of different groups. State what criteria are used in viral classification. The cell wall in algae is generally made up of polysaccharides. Pigmentation and Photosynthetic Apparatus: Type # 6. Fritsch (1935, 1945) in his book “The Structure and Reproduction of the Algae” proposed a system of classification of algae. 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. Class: Pucciniomycetes. 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]. Nature of Reserve Food: The primary product of photosynthesis i.e., starch is same in all groups of … Among the carotenoids, β carotene is found in all classes of algae.

Photosynthetic pigments: They possesses chlorophyll a, chlorophyll b and small amount of β-carotenoids. The heterotrophic eukaryotic, multicellular organisms lacking a cell wall are included in the Kingdom Animalia. The biloproteins are water soluble pigments and can be phycocyanin, phycoerythrin and allophycocyanin. In Chlorophyceae there are 2-6 thylakoids per granum and the pyrenoids are covered with starch plates. ... Kingdom Plantae (Algae, Bryophytes, ferns, gymnosperms, Multicelled eukaryotes) Cell structure: cellulosic cell wall, presence of plastids . Some are unicellular eg. Cyanophyceae or blue green algae are prokaryotic in nature whereas all other classes of algae are eukaryotic. They are commonly found in aquatic environments including freshwater, marine and brackish water. e Carotene is present in Bacillariophyceae. The chromatophores of different classes of algae differ in number of thylakoids per granum. … Some acellular organisms like viruses and viroids as well as the lichens are not included in the five kingdom system of classification. One of the best known algal classification was proposed by Fritsch who divided them into 11 classes (1945). (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.

Chlorophyceae or green algae, e.g. In Phaeophyceae cell wall contains alginic acid and fucinic acid. Classification is based on the following criteria: Plant body: Presence or absence of a well-differentiated plant body. Chlorophyceae (Green algae) General characterstics of Chlorophyceae. The plant body is thallus, they may be filamentous, colonial, branched or unbranched. 1. Membrane bound cell organelle like chloroplast, mitochondria and ER are absent. The contents of this documents are Dichotomous Key to Freshwater Algae, Groups of Cyanobacteria & Algae, Dinoflagellates, Euglenoids, Brown, Golden brown, and Yellow brown Algae … The flagella can be acronematic (Fig. The type, number and position of flagella are important basis for separation of different classes of algae. Eleven classes proposed by Fritsch are as follows: Welcome to BiologyDiscussion! The pigments in algae can be chlorophylls, carotenoids and biloproteins. The use of algae in integrated aquaculture has also been recently reviewed by Turan (2009). 2. The reproduction is oogamous and life cycles are usually complex in Rhodophyceae and Phaeophyceae. Classification of Algae: Class. Nothing could be further from the truth. Botany, Class 11 Chlorophyceae 2. Single-celled microorganisms were the first forms of life to develop on earth, approximately 3 billion–4 billion years ago. As the group implies, microorganisms are Levels of Classification of Plants: There are three levels of classification among plants. Algae are the simplest multicellular plants. These are common only in Rhodophyceae and Cyanophyceae. Classification of Plant Groups- Cryptogamae and Phanerogamae In 1883, A.W. This division has all unicellular flagellates. Type of Life Cycle and Reproduction: The best answers are voted up and rise to the top. Sub Phylum B: Plasmodroma. There is three main Algae classification: Chlorophyceae – These are called green algae, due to the presence of pigments chlorophyll a and b. In all other classes the basic flagellar structure is similar. The cell wall in Chlorophyceae is made up of cellulose. 5 Stages in Life cycle of Puccinia. In Phaeophyceae the reserve food material is laminarin or mannitol. In Xanthophyceae oil and leucosine are reserve food materials. This article throws light upon the top six types of Classification of Algae. Euglenophyta. In Rhodophyceae the cell wall is made of non-cellulosic polysaccharides like xylans and galactans. Some species shows Alternation of generations in their life cycle. Algae are photosynthetic eukaryotic organisms. Root, Stem and Leaves. • 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 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. On the basis of nuclear organization algae can be prokaryotic or eukaryotic. Most forms of algae are aquatic so they are living in fresh water and in sea water too. Examples are Chlamydomonas, Spirogyra, and Chara Phaeophyceae – Also called as brown algae, they are predominantly marine. Pheophyceae are called commonly known as brown algae. Scientists have been trying to classify living organisms in various ways for centuries. This supergroup includes heterotrophic predators, photosynthetic species, and parasites. E.g. Name the types of nitrogenous bases present in the RNA. Some of the motile and non-motile algae may form a colony known as Coenonbium. Many of the protist species classified into the supergroup Excavata are asymmetrical, single-celled organisms with a feeding groove “excavated” from one side. Some of the characteristics are: Classification of Phylum Protozoa. In Xanthophyceae flagella are two, unequal apical one acronematic and one pantonematic i.e., heterokontic. Family: Pucciniaceae. Algae possess the usual eukaryotic structures - Golgi apparatus, mitochondria, … • Green algae can be unicellular, colonial and multicellular. Classification is based on pigments, flagella and reserve food material.
