The chromatophores of different classes of algae differ in number of thylakoids per granum. Chlorophyceae (green algae) Phaeophyceae (brown algae) Rhodophyceae (red algae). In Xanthophyceae oil and leucosine are reserve food materials. Class 2: Sarcodina. Haplontic life cycle, diplontic life cycle and triphasic life cycles are characteristic of different groups. TOS4. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. Chlorophyll a is present in all classes of algae. Many of the protist species classified into the supergroup Excavata are asymmetrical, single-celled organisms with a feeding groove “excavated” from one side. Which organelle is known as “power house” of the cell? tonematic flagella, (C). In Xanthophyceae, Phaeophyceae and Bacillariophyceae there are 3 thylakoids per granum and pyrenoids are without starch plates. 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) Share Your PDF File A plant kingdom is further classified into subgroups. The flagella have 9 + 2 pattern of component fibrils. Essay on Harmful Aspects of Algae | Biology. In Xanthophyceae pectic substance is more common. The type, number and position of flagella are important basis for separation of different classes of algae. The first level of classification among plants depends on whether the plant body has well-differentiated, distinct components. The kingdom-Plantae has been described under algae, bryophytes, pteridophytes, gymnosperms and angiosperms. It is the largest class of algae; They are commonly known as green Algae. Algae, bryophytes, pteridophytes, gymnosperms and angiosperms are included in this group. As the group implies, microorganisms are Colour. In Prasinophyceae, prasionate type flagella are found. Nuclear Organization 2. Algae exist in environments ranging from oceans, rivers, and lakes to ponds, brackish waters, and even snow. Before sharing your knowledge on this site, please read the following pages: 1. Green. The pigments in algae can be chlorophylls, carotenoids and biloproteins. Protozoa Definition. Nature of Cell Wall Components 3. 4. 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. Kingdom: Fungi. 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 Cryptophyta. The flagella can be acronematic (Fig. 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. Classification is based on pigments, flagella and reserve food material. 1. classification based on pigmentation 2. classification based on cell wall 3. classification based on nature of flagellum 4. classification based on food resevoir. (adsbygoogle = window.adsbygoogle || []).push({}); On the basis of photosynthetic pigments algae classified into three classes. Algae are photosynthetic eukaryotic organisms. The carotenoids are of two kinds: Carotenes and Xanthophyll’s. In this article we will discuss about the Fritsch’s and Smith’s classification of algae. This article throws light upon the top six types of Classification of Algae. For instance, algae living in snow contain carotenoid pigments in addition to chlorophyll, hence giving the surrounding snow a distinctive red hue. 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. Bryophyta Classification of Plant Groups- Cryptogamae and Phanerogamae In 1883, A.W. 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. Chlorophyll e is confined to Tribonema of Xanthophyceae. This division has all unicellular flagellates. 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. Xanthophyceae or yellow—green algae e.g. 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 … Fritsch (1935, 1945) in his book “The Structure and Reproduction of the Algae” proposed a system of classification of algae. The heterotrophic eukaryotic, multicellular organisms lacking a cell wall are included in the Kingdom Animalia. What is a mushroom shaped gland? Examples are Chlamydomonas, Spirogyra, and Chara Phaeophyceae – Also called as brown algae, they are predominantly marine. They include bacteria, fungi, algae, and protozoa; microscopic plants, and animals. Nature of Reserve Food: The primary product of photosynthesis i.e., starch is same in all groups of … Hierarchies of Life Protista due to the fact that the kingdom is so diverse, and there was a mixture of results for specific species. In fact, even Aristotle classified living organisms on the basis whether they lived on land, water or air. Nature of Reserve Food. This supergroup includes heterotrophic predators, photosynthetic species, and parasites. But biologists wanted a broader system of classifying living organisms. 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]. In Chlorophyceae there are 2-6 thylakoids per granum and the pyrenoids are covered with starch plates. Cyanophyceae or blue green algae are prokaryotic in nature whereas all other classes of algae are eukaryotic. Many scientists have spent their … Classification of Kingdom Plantae. The classification of algae can be done in many ways since there is a millions of kind. Class 1: Mastigophora. DNA fibrils are free in nucleoplasm and are not associated with histones. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. 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. 11. In Cyanophyceae the thylakoids are free in cytoplasm as chloroplasts are not found and pyrenoids are also absent. Scientists have been trying to classify living organisms in various ways for centuries. In Chrysophyceae cell wall is non-cellulosic which is silicified or calcified. On the basis of nuclear organization algae can be prokaryotic or eukaryotic. 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. Photosynthetic pigments: They possesses chlorophyll a, chlorophyll b and small amount of β-carotenoids. There are unicellular algae as well as muticellular filamentous 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.
