Statement I: In Spirogyra , sometimes the gametes behave directly as zygospores without fusion. Statement II: In Spirogyra , asexual reproduction is by flagellated zoospores produced in zoosporangia. Select the correct option regarding both the statements.
Options
- ABoth the statements are correct
- BBoth the statements are wrong
- CStatement I is correct and II is wrong
- DStatement II is correct and I is wrong
Correct answer
A. Both the statements are correct
Step-by-step solution
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.
