Question

Assertion : Megaspore mother cell undergoes meiotic division.
Reason : All four megaspres form female gametophyte.

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

Answer 1

The correct option is C Assertion is true but Reason is false

One hypodermal nucellar cell of the micropylar region differentiates into the sporogenous cell. It forms a diploid megaspore mother cell or megasporocyte. The megaspore mother cells undergo meiosis and formed a row of four haploid megaspores. Only the chalazal megaspore remains functional megaspore enlarges and gives rise to female gametophyte, also called embryo sac.
