In Spirogyra, vegetative reproduction usually takes place by fragmentation or by the formation of different types of spores. Asexual reproduction is by flagellated zoospores produced in zoosporangia.
In Spirogyra, sexual reproduction takes place through the fusion of two gametes to form zygospores. These gametes are non-flagellated (non-motile) but similar in size and sometimes the gametes behave directly as zygospores without fusion.
