The vegetative organization or plant body is known as thallus. Thallus is a unbranched multicellular filamentous structure formed at hand arrangement of cylindrical cells head to head in a single row. Each cell is covered not later than cell wall.

Cell try is double layered, outer layer is made up of pectin and inner layer is made up of cellulose. Exterior to the cell wall, there is layer of mucilaginous sheath which make the organism slippery. So, they are commonly called as water silk as they are slimy in kidney.

Spirogyra: Life Cycle...

In Spirogyra, the sexual reproduction involves a cycle alternation between a haploid vegetative filament gametophyte plant and a diploid zygospore, towards the end of growing season the Spirogyra filament produce aplanogametes in vegetative cells called gametangia The gametes fuse to form a zygospore 2n. Fragmentation happens in different ways. Under un-favourable conditions, the protoplast of each vegetative cell shrinks and develops a wall around it to form an aplanospore.

On return of favourable condition the diploid nucleus of zygospore undergo meiosis to produce 4 haploid nuclei out of which 3 degenerate.
