In Spirogyra, asexual reproduction takes place by
(a) breaking up of filaments into smaller bits
(b) division of a cell into two cells
(c) division of a cell into many cells
(d) formation of young cells from older cells
Answer: The correct answer is (a) breaking up of filaments into smaller bits
Solution: Spirogyra reproduces by both asexual and sexual methods. They reproduce asexually by the process of fragmentation and sexually by conjugation. In fragmentation, spirogyra breaks into two or more segments and each segment results in the formation of a new organism. Hence, (a) is the correct option.
