Blue-green algae contains different types of pigments such as chlorophyll-a, β-carotene, xanthophyll’s and phycobilins, c-phycoerythrin and c-phycocyanin. Cyanophyceae or Myxophyceae (Blue-green algae) These are unicellular, colonial or multicellular bodies. Scenedesmus Palmelloid type: In this case, algae cells are surrounded by a viscous mucilaginous substance such as Teyraspora, Aphanothce , etc. Sexual reproduction has yet to … ... (glauco- comes from the Greek glaukos meaning blue-green). Green algae are characterized by unicellular flagellated cells or microscopic colonies of flagellated or non-flagellated cells and reproduce by zoospores. These include motile vegetative cells that produce vegetative spores and/or gametes (e.g. Brown algae (Pheophyceae) are characterized by the presence of motile reproductive phase with two lateral flagella. The mitochondrial and chloroplast is double membraned. ; They also contain contain chlorophyll pigment and hence green in colour. Their nucleus is prokaryotic. Green tides resulted from bloom floating Ulva have caused substantial economic losses. Motile Unicellular Algae. The green algae, Ulva spp., have been causing environmental problems worldwide, e.g., green tides and biofoulings. Some of them are unicellular and live as a single cells, while others form a colony or a long filament. The two motile algae presented in this gallery are Euglena and Trachelomonas, both members of the phylum Euglenaphyta. Chlamydomonas), non-motile vegetative cells that produce Unicellular, motile, phototropic green algae were extracted from soil samples taken at metre intervals along a 25-m transect in a wheat ®eld. Green algae, members of the division Chlorophyta, comprising between 9,000 and 12,000 species. Many species of green algae are motile and they possess flagella, which is a lash-like appendage used for locomotion. Explanation: Unicellular algae are found growing in marshy area. Non-motile Colonial: In colonial forms, the number of unicellular algae is indefinite, and they are non-motile such as Scenedesmus, Hydrodictyon (water net), etc. Ulva foulings increase the maintenance cost of marine facilities and contribute to the biomass of floating algae. They are important in the food chain of the freshwater habitats, providing nutrition for a wide variety of … The red and green algae include unicellular, multicellular, and colonial forms. They are plant-like autotrophs and also produce their own food. A unicellular non-motile algae is chlorophycea. ; Both multicellular and unicellular species are found in such algae cases. Motile cells have two whiplash flagella. Green algae are thought to have the progenitors of the higher green plants but there is currently some debate on this point. Non-motile Green Algae. Red algae (Rhodophyceae) are characterized by the absence of any motile phase. Considered for its potential as a source of food for an expanding world population. Glaucophyta. Chlorella - Thought to have arose from a green flagellate such as Chlamydomonas by lose of their flagella. Chloroplast of these algae contain pigmentsm chlorophyll ‘a’ and ‘b’, which give them a bright green color. The green algae are well represented in the marine plankton and damp terrestrial environments, with many species occurring as unicellular organisms. Desmids - aquatic free floating green algae, mostly unicellular found in ponds and lakes. The vegetative growth of 61 randomly selected isolates 11. Non-motile cells have a rigid cell wall composed of cellulose.
