In Prasinophyceae, prasionate type flagella are found. Essay on Harmful Aspects of Algae | Biology. 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. Classification of Kingdom Plantae. Xanthophyceae 3. There is three main Algae classification: Chlorophyceae – These are called green algae, due to the presence of pigments chlorophyll a and b. 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. In some cases lipids and proteins are also present in them. Chlorophyceae (green algae) Phaeophyceae (brown algae) Rhodophyceae (red algae). Gaurab Karki But biologists wanted a broader system of classifying living organisms. Hence came the five kingdom classification. Microorganisms are very diverse. The nature of reserve food can be a criterion for distinction of different groups of algae. Haplontic life cycle, diplontic life cycle and triphasic life cycles are characteristic of different groups. In this article we will discuss about the Fritsch’s and Smith’s classification 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. Levels of Classification of Plants: There are three levels of classification among plants. They produce their own food by photosynthesis, hence they can be known as Autotrophic. One of the best known algal classification was proposed by Fritsch who divided them into 11 classes (1945). Like plant cells, some euglenoids are … In Cyanophyceae or blue green algae the cell wall is more like bacteria and is made up of mucopeptides. Name the types of nitrogenous bases present in the RNA.

The Gram stain characterizes bacteria based on the structural characteristics of their cell walls. Disclaimer Copyright, Share Your Knowledge The presence or absence of pigments which impart colour to the algae forms the main basis of classification of 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. The use of algae in integrated aquaculture has also been recently reviewed by Turan (2009). it is a traditional system as well as a phylogenetic system of classification of plants. 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. It is the largest class of algae; They are commonly known as green Algae. There are unicellular algae as well as muticellular filamentous algae. In Cyanophyceae the thylakoids are free in cytoplasm as chloroplasts are not found and pyrenoids are also absent. Order: Pucciniales. Algae are usually green, but they can be found in a variety of different colours. For instance, algae living in snow contain carotenoid pigments in addition to chlorophyll, hence giving the surrounding snow a distinctive red hue. e Carotene is present in Bacillariophyceae.

Our mission is to provide an online platform to help students to share notes in Biology. • 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 The flagella have 9 + 2 pattern of component fibrils. Pigmentation and Photosynthetic Apparatus 4. Chlorophyll e is confined to Tribonema of Xanthophyceae. The cell wall in Chlorophyceae is made up of cellulose. Eleven classes proposed by Fritsch are as follows: 1. As the group implies, microorganisms are The heterotrophic eukaryotic, multicellular organisms lacking a cell wall are included in the Kingdom Animalia. In fact, even Aristotle classified living organisms on the basis whether they lived on land, water or air. In Chlorophyceae flagella are 2 (Fig. Table of Contents hide. Many scientists have spent their … Classification of Plant Groups- Cryptogamae and Phanerogamae In 1883, A.W. Euglenophyta.

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. 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. Thus, they are among the large producers on the earth; especially in aquatic habitat. 11. Some of the characteristics are: Classification of Phylum Protozoa. These pigments are present in sac like structures called thylakoids. 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. The type, number and position of flagella are important basis for separation of different classes of algae. Green. flagellum. • Green algae can be unicellular, colonial and multicellular. Nuclear Organization 2. Scientists have been trying to classify living organisms in various ways for centuries. Colour.

Bryophyta tonematic flagella, (C). Algae are the simplest multicellular plants. In Chrysophyceae cell wall is non-cellulosic which is silicified or calcified. They are unicellular as well as multicellular. His classification of algae is mainly based upon characters of pigments, flagella and reserve food material. Chlorophyceae (Blue Green Algae) Chlorophyll-a and b. The chromatophores of different classes of algae differ in number of thylakoids per granum. Cyanophyceae or blue green algae are prokaryotic in nature whereas all other classes of algae are eukaryotic. 1. classification based on pigmentation 2. classification based on cell wall 3. classification based on nature of flagellum 4. classification based on food resevoir. These are eukaryotic organisms, autotrophic in […] Algae, bryophytes, pteridophytes, gymnosperms and angiosperms are included in this group. Economic Importance of Algae: Almost 50% of carbon fixation on earth is carried out by algae. Classification is based on pigments, flagella and reserve food material. The plant body is thallus, they may be filamentous, colonial, branched or unbranched. 2A), 4 or indefinite in number, apical or sub-apical in position and acronematic type i.e., isokontic. 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. The pigments in algae can be chlorophylls, carotenoids and biloproteins. E.g. Algae possess the usual eukaryotic structures - Golgi apparatus, mitochondria, … As these xanthophyll’s are restricted to certain classes, the xanthophyll’s are important diagnostic characteristics of algae. Classifications of algae as Proposed by some workers are: F.E. Properties and Classification of Microorganisms Since the cell is the basic unit of all living things, you might think it is a simple structure. Classification is based on the following criteria: Plant body: Presence or absence of a well-differentiated plant body. Some of the motile and non-motile algae may form a colony known as Coenonbium. 1.
