Blue-Green Algae: The “A” that shouldn’t be in “Harmful Algal Bloom” Prokaryotes • Only organisms within all types of algae that are prokaryotes • Bacteria • Conduct photosynthesis • Primary producers • Produce oxygen Blue-Green Algae = Cyanobacteria Not an “A” at All Snowella species. His classification was based on such criteria as pigmentation, types of flagella, assimilatory products, thallus structure and methods of reproduction. They are the food base of ecosystems called kelp forests (see Figure below). Algae have been divided into groups based mainly on distinctive plastid accessory pigments. Automated recognition and classification system for algae will be one of the several tools to be developed for monitoring algae diversity of and hence, water quality changes, the lake. According to these morphological and physiological differences they are classified by many people. Most live in fresh water, but some are found in marine and soil habitats. classification of algae was given by F.E Fritsch (1935) in his book ‘The Structure and Reproduction of the Algae’. There is still an ongoing battle about the composition of eukaryotic supergroups, for example, and until that is resolved, it can be hard to define taxonomic levels included within supergroups. Algae are photosynthetic organisms belonging to the kingdom Protista. Rhodophyta–The Red Algae •Marine algae present all over the world •Contains pigments chlorophyll-a, chlorophyll-d, and phycobilin. Microalgae can also be used to produce biofuel. On the basis of the organisation of the vegetative thallus, the morphology of reproductive structures, the way of spores production and particular life cycle involved the kingdom mycota is classified into following divisions..

Diatoms are much more common than golden-brown algae and consist of many types of plankton found in the ocean. Ecology of Algae. Plant Kingdom is divided in to: (I) Thallophyta: Various types of microorganisms like algae, fungi and bacteria have been kept under it. Algae type Cyanobacteria All other classifications. It grows naturally and is inexpensive. Yellow-green algae or the Xanthophyceae (xanthophytes) are an important group of heterokont algae. Classification of Algae For diverse reasons, the taxonomy of algae is not settled yet. Fritsch (1935) classified the whole of the algae into eleven classes on the basis of type of pigments, nature of reserve food material, mode of reproduction etc. It includes the simplest type of fungi. Fritsch (1935, 1945) in his book “The Structure and Reproduction of the Algae” proposed a system of classification of algae. Methods. They vary from single-celled flagellates to simple colonial and filamentous forms. Because of these pigments, many groups of algae have been known by their color: hence red, green, brown, etc. Fritsch’s Classification of Algae: F.E. absent According akinetes algae algal anisogamy antheridia apical arranged Asexual attached axis basal bearing becomes blue-green algae body Bold and Wynne branches brown called cell wall central Chapman Chlamydomonas Chlorophyceae chloroplast chromatophores Class classification colony common conjugation consists contains culture cytoplasm develop diatoms diploid divides division … Algae, singular alga, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista.Algae have many types of life cycles, and they range in size from microscopic Micromonas species to giant kelps that reach 60 metres (200 feet) in length.

This study is also an extension of previous studies by other workers who focused on certain algal taxa only. He considered that as a group algae deserve the rank of division. Dr. Poonam Jaiswal, Lecturer Botany, JDB Govt. The major characteristics of taxonomic significance used in the classification of algae have been tabulated in Table 5.2. Algal Research is an international phycology journal covering all areas of emerging technologies in algae biology, biomass production, cultivation, harvesting, extraction, bioproducts, biorefinery, engineering, and econometrics. c) Are mostly aquatic, found in fresh as well as marine water. The advantage of using algae is that it is an available source. In this article we will discuss about the Fritsch’s and Smith’s classification of algae. He divided it into 11 classes based on pigments,reserve food materials and flagellar types. Learn with Videos. Xanthophyte chloroplasts contain the photosynthetic pigments chlorophyll a, chlorophyll c, β-carotene, and the carotenoid diadinoxanthin. b) Photosynthetic organism synthesizing their own food. They can be classified in several ways by different criteria such as structural characteristics, membrane composition, pigments color, and energy-storing molecules. Alga is the singular of algae with a changing size from microscopic unicellular micro-algae (Chlorella and Diatoms) to large massive kelps that are usually a length extending in meters (200 feet) and then there's brown alga. 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 can be found in aquaculture supplying oxygen and acting as a natural food base for such cultured animals as dinoflagellates that cause the red tides Divisions of Algae o Green algae - May be unicellular or multicellular Have cellulose cell walls, contain chlorophyll a and b, and store starch like plants. Instead of a cell wall, diatoms are encased by a silica shell, known as a frustule, that … Modern classifications delimit them with many other characters such as cell wall Example Definitions Formulaes. Page 3/5. Classification • 20+ classes of green algae have been described since Linnaeus •Many criteria have been used to establish classes – Morphlhology – Ultrastructure • + mitosis, cell division, cytokinesis, flagellar apparatus –Life history patterns – Molecular 2 •Primarily rRNA genes, rbcL The term algae (or seaweeds) is a practical term to use in everyday language, even if it has lost all clear meaning in the new phylogenetic classification of living organisms! Both are found in fresh and salt water environments. Classification of Algae . Ø Different groups of algae have different pigment composition. ii. F.E. Algae can also be used to produce fuel, this will be discussed in chapter 6. Algae play significant roles as producers in aquatic ecosystems.Microscopic forms live suspended in the water column.
