More than 10,000 species are described in this class. division and on this basis classified different categories based on observation The phylum Opalozoa was established by Cavalier-Smith in 1991. They occupy a wide variety of habitats, including fresh water (lakes, reservoirs, and rivers), oceans, estuaries, moist soils, coastal spray The 6 divisions are : Cyanophyta, Glaucophyta, Chromophyta, Rhododphyta, Chlorophyta and Charophyta. In this article we will discuss about the classification of algae. For solving any problem we have to understand that problem first, but when we talk about The problem of country which means the problem of 130 crore population, then it become complex.

A generally agreed classification of algae recognizes nine broad taxonomic groups, called Divisions. General characteristics of algae, Classification of algae based on habitat, Thallus diversity in algae, Chloroplast shape variations in algae, Pigmentation in algae, Reproduction in algae, Life cycle in algae. It was Leeuwenhoek, 1674 who first observed unicellular algae under the microscope. Ø Different groups of algae have different pigment composition. Pyrophyta: Dinophyceae and Desmophyceae. 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. He did not use the term algae. They are mainly of aquatic habitat may be freshwater or marine, some are also terrestrial and are grown over moist soil, stone or wood. Introduction .

Identification of Algae in Water Supplies Section I Continue George Izaguirre The algae are a large and very diverse group of organisms that rangefrom minute single-celled forms to the giant marine kelps. Algae possess diverse characters in their pigments, nature of reserve food, nature of cilia etc. Welcome. The divisions and classes are the following. The student is probably familiar with the seaweeds of the seashore and may even have observed green skeins in stagnant freshwater ponds and pools. modifications to the Pascher and smith classification Fritsch classification In their classification it is also used the comparison of their genomes to show evolutionary history. We may say that algae … He divided algae into seven divisions: (1) Chlorophyta consisting of two classes: 1. The account of algae dates back to ancient Chinese literature and it is a believe that along with the origin of plant sciences, the recognition of algae as a group has taken place. Chlorophyceae (Green algae) General characterstics of Chlorophyceae. In this process energy is released therefore termed as exothermic process while both Anabolism and Catabolism occur therefore called Amphibolic pathway . ALGAE are thalloid structure, containing chlorophyll, performing photosynthesis. F.E Fritsch, he believes about the algae is different from Whittaker and woese Algae possess diverse characters in their pigments, nature of reserve food, nature of cilia etc. proposed by Gilbert Morgan Smith appear as:-. These plants, which are among the simplest in the plant kingdom, belong to the group known as Algae. Smith proposed the classification of algae taking into consideration the evolutionary principles proposed by Fascher (1914).

Fritsch’s Classification of Algae: F.E. Answer. Chlorophytes, Rhodophytes, Phaeophytes are common in the classification of algae. The contents of this documents are Dichotomous Key to Freshwater Algae, Groups of Cyanobacteria & Algae, Dinoflagellates, Euglenoids, Brown, Golden brown, and Yellow brown Algae … According to these morphological and physiological differences they are classified by many people. 3. It is the largest class of algae; They are commonly known as green Algae. •The major groups of algae have been classified into Divisions (the equivalent taxon in the zoological code was the Phylum). Greeks called the “Phycos” for seaweeds. For Brain construction neural cells are used, these are the special types of cells explained in three divisions:- Cell body, Dendrites and Axon, about this we see in another article. Smith, G.M. Gilbert Morgan Smith (6 January 1885, Beloit, Wisconsin – 11 July 1959) was a botanist and phycologist, who worked primarily on the algae.He was best known for his books, particularly the Freshwater Algae of the United States, the Marine Algae of the Monterey Peninsula and the … Examples are Chlamydomonas, Spirogyra, and Chara; Phaeophyceae – Also called as brown algae, they are predominantly marine. Algae exist in a variety of shapes and forms—single-celled algae may be spherical, rod-shaped, or spindle-shaped, while multicellular algae may appear as colonies, filaments or tubes. For example, some phycologists place the classes Bacillariophyceae, Phaeophyceae, and Xanthophyceae in the division Chromophyta, whereas others place each class in separate divisions: Bacillariophyta, Phaeophyta, and Xanthophyta. Blue Green Algae Classification. Smith classified algae into seven divisions. a) Chlorococcales b) Chamaesiphonales c) Hprmogonales. iv. 8. Van den Hoek (1995) classified algae into 11 divisions: … less plant. Fritsch divided it into 5 orders Then how we resolve this huge problem, Some great writer had said  that the solution of every question lie within the Nature, so after long observation i found the solution within the god great creation 'Th. This process get completed within Cytoplasm and Mitochondria . definition of algae is not clear. Chlorophyta: Chlorophyceae and Charophyceae, 2. Algae range from single-celled organisms to multi-cellular organisms, some with fairly complex differentiated form. Photosynthetic pigments: They possesses chlorophyll a, chlorophyll b and small amount of β-carotenoids. 1980 - Lee used fine structural aspects of organelles such as chloroplast, ER, flagellum, eyespot and nucleus to classify the algae into 6 divisions and 15 classes. His classification was based on such criteria as pigmentation, types of flagella, assimilatory products, thallus structure and methods of reproduction. organisms' FIVE kingdoms were kept forth. In this paper, we used a convolutional neural network to study the classification of marine microalgae by using low-resolution Mueller matrix images. Algae exist in environments ranging from oceans, rivers, and lakes to ponds, brackish waters, and even snow. Algae of uncertain position (i) Chloromonadales (ii) Cryptophyceae . The main reason behind this huge habitat are their carriers, for Chlorophyceae (green algae) Phaeophyceae (brown algae) Rhodophyceae (red algae). This story of classification reached to A.W Eichler, in But Smith divided it into 3 orders. PNAS, v.36 #4 pp.246-248. Round’s Classification (1973) 4.

Just as humans move from one place to another using our legs, algae move from one … They have chlorophyll a, c, carotenoids and xanthophyll pigments. INTRODUCTION. Xanthophyceae or yellow—green algae e.g. Pyrophyta: Dinophyceae and Desmophyceae, Smith included certain algae of uncertain position into Chloromonadales and Cryptophyceae. The classification of algae proposed by Smith (1933, 51, 55) is based on the physiological characters of vegetative cells and the morphology of motile reproductive cells. He treated algae giving rank of division and divided it into 11 classes. importance of pigments. Bold and Wynne’s Classification (1985) 5. Be the first to answer this question. GM Smith (1950)classified algae intoseven divisions. performing photosynthesis. In addition, algae may occur in moist soil or on the surface of moist rocks and wood. The kingdom Plantae is further classified into:-. Mueller matrix images of 12 species of algae from 5 families were measured by a Mueller matrix microscopy with an LED light source at 514 nm wavelength. Chlorophyceae (Green algae) General characterstics of Chlorophyceae. Algae are usually green, but they can be found in a variety of different colours. Inside skull Brain is covered by Cranial Meninges which function as a protective layer. Ø Algae also shows great diversity in pigmentation. Division-level classification, as with kingdom-level classification, is tenuous for algae. The division Cyanophyta includes only one class Cyanophyceae. o cell wall composition and structure. There is three main Algae classification: Chlorophyceae – These are called green algae, due to the presence of pigments chlorophyll a and b. ii. a) Chlorococcales b) Hormogonales. plants, The quest to classify algae begins in the sixteenth Ø The classification of algae by Fritsch is primarily based of the pigmentation in algae. Botrydium. century by the most brilliant biologist LINNAEUS in 1753 of whom, four genera These are Chlorophycophyta, Xanthophycophyta, Bacillariophycophyta, Phaeophycophyta, Rhodophycophyta, Chrysophycophyta, Euglenophycophyta, Cryptophycophyta and Pyrrophycophyta.
