Question

Assertion: In plants, apomixis is a form of asexual reproduction that mimics sexual reproduction.
Reason: Apomixis involves the production of seeds without the fusion of gametes.

• A. Both assertion and reason are true and reason is the correct explanation of assertion
• B. Both assertion and reason are true but reason is not the correct explanation of assertion
• C. Assertion is true but reason is false
• D. Both assertion and reason are false

Answer 1

The correct option is A Both assertion and reason are true and reason is the correct explanation of assertion

Apomixis (Apo- without, mixis- fusion) is a mode of reproduction in some plants which results in the formation of seeds without genetic fusion. Apomixis is a form of asexual reproduction that mimics sexual reproduction but produces seeds without fertilisation. Apomictic seeds develop in many ways- (1) Diploid egg cells are formed due to endoreplication that divide and form embryo without fertilisation or (2) Nucellar cells surrounding the embryo sac start dividing and protrude into embryo sac and develop into the embryos.
