An akinete is a thick-walled dormant cell derived from the enlargement of a vegetative cell.〔Moore, R. et al. (1998) ''Botany.'' 2nd Ed. WCB/McGraw Hill. ISBN 0-697-28623-1〕 It serves as a survival structure. It is a resting cell of cyanobacteria and unicellular and filamentous green algae.〔Elfgren, I. K. (2003) ''Studies on the Life Cycles of Akinete Forming Cyanobacteria.'' Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 856, Acta Universitatis Upsaliensis. ISBN 91-554-5665-0〕 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, and have a normal cell wall surrounded with 3 layer coat. == References == 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Akinete」の詳細全文を読む スポンサード リンク
