#cyanobacteria #bluegreen #algae • Description: • Cyanobacteria: • The cyanobacteria are the largest and most diverse group of photosynthetic bacteria which was • previously known as ‘blue green algae’. • Cyanobacteria are true prokaryotes. They vary greatly in shape and appearance. • They range in diameter from about 1-10um and may be unicellular, exist as colonies of many shapes, or form ilaments consisting of trichomes (chains of cells) surrounded by mucilaginous sheath. • They have normal Gram-negative type cell wall. They lack lagella and • often use gas vesicles to move in the water, and many filamentous species have gliding motility. • Their photosynthetic system closely resembles that of eukaryotes because they have chlorophyll • a and photosystem II. • They carry out oxygenic photosynthesis, i.e., they use water as an electron donor and generate oxygen during photosynthesis. Cyanobacteria use phycobilins as accessory pigments. • Photosynthetic pigments and electron transport chain components are located in thylakoid membranes linked with particles called phycobilisomes. • Phycocyanin pigment (blue) is • their predominant phycobilin and C02 in them is assimilated through the Calvin cycle. • Reserve food material in cyanobacteria is glycogen. Cyanobacteria reproduce by binary fission,fragmentation. • In cyanobacteria hormogonia, akinetes and heterocysts are present. • ‪@diamondrocksbiology‬ • Your queries: • cyanobacteria, • cyanobacteria aquarium, • blue green algae • cyanobacteria (organism classification) • cyanobacteria bloom, • cyanobacteria slime, • cyanobacteria video, • cyanobacteria couses, • harmful cyanobacteria, • cyanobacterial bloom • Complete chapter 6 class 11 • Kingdom prokaryota(monera): • • Kingdom Monera | kingdom prokaryota |...
