Question

Assertion : Megaspore mother cell undergoes meiotic division
Reason : All four megaspores form female gametophyte.
A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C. If the assertion is true but the reason is false
D. If both the assertion and reason are false

Answer 1

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