CBSE Class 10 Science 2017 · Paper 31/1/1 · Question 2
Name the method by which spirogyra reproduces under favourable conditions. Is this method sexual or asexual ?
Answer
Spirogyra reproduces by fragmentation, which is an asexual method.
Under favourable conditions Spirogyra reproduces by fragmentation: the mature filament breaks up into small pieces (fragments), and each fragment grows into a new filament. The method is asexual, because only one parent is involved and no gametes are formed or fused.
