(a) : In Spirogyra, gametes are non­motile and sexual reproduction takes place by conjugation. Sargassum belongs to Phaeophyceae group of algae. They are commonly called as ‘brown algae’ and contain photosynthetic pigments chlorophyll a andc.

It enriches its habitat with nitrogen by fixing atmospheric nitrogen and also causes water bloom.
