Assertion : Algae and fungi switch to asexual method of reproduction before the onset of adverse conditions.
Reason : Asexual reproduction may introduce variations and leads to the formation of many clones.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
d
During favourable conditions, algae and fungi multiply asexually but during unfavourable conditions gametes are formed. The gametes fuse to form zygotes which often develop a thick wall to become zygospores. The latter are dispersed. Under favourable conditions zygospore germinates to form new organisms. Sexual reproduction induces variations which may help in survival of organism.
