| Read the assertion and reason carefully: |
| 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
E) If the assertion is false but reason is true
Correct Answer: C
Solution :
One hypodermal nucellar cell of the micropylar region differentiates the sporogenous cell. It forms a diploid 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 megasporeenlarges and gives rise to female gametophyte, also called embryo sac.
