I-Phylum: -Cyanobacteria -Cells small usually < 10μm -lacking nucleus, chloroplasts or other membrane bound organelles. -often with heterocysts or akinete spores -Blue green in colour due to a water soluble accessory pigment (phycocyanin)-Growth form as unicells, small clusters filaments, or large colonies. -photoautotrophs, aerobic

Classification of Blue- green algae: -Phylum: Cyanobacteria -Class: Myxophyceae 1 - Order: Chroococcales - Family: Chroococcaceae 2 - Order: Oscillatoriales a- Family: Oscillatoreaceae b- Family: Nostocaceae ex: Gleocapsa ex: Oscillatoria ex: Nostoc ex: Anabaena

Cyanobacteria Reproduction Asexual reproduction 1 - Exospores: bud off the end of a filament 2 - Endospores : subdivision of cell into multiple units 3 - Akinetes: large, thick-walled cells 4 - Hormogonium: short filament from breakup of longer trichomes at specialized or dead cells. 5 - fragmentation.
