Akinete
From Wikipedia, the free encyclopedia
An akinete is a thick-walled dormant cell derived from the enlargement of a vegetative cell.[1] It serves as a survival structure. It is a resting cell of cyanobacteria and unicellular and filamentous green algae.[2] Under magnification, akinetes appear thick walled with granular-looking cytoplasms.
DEVELOPMENT OF AKINETES FROM A VEGETATIVE CELL INVOLVES:-
*increase in size *gradual disappearance of gas vacuoles *increase in cytoplasmic density, number of ribosomes & cyanophycin granules
The akinetes are filled with food reserves,have normal cell wall surrounded with 3 layer coat.
