Biology Question on Meiosis
Megaspores are produced from the megaspore mother cells after
A
mitotic division
B
formation of thick wall
C
differentiation
D
meiotic division.
Answer
meiotic division.
Explanation
Solution
One hypodermal nucellar cell of the micropylar region of ovule differentiates as the sporogenous cell. It forms a diploid megaspore mother cell or megasporocyte. The megaspore mother cell undergoes meiosis and forms a row of four haploid megaspores. Only the chalazal megaspore remains functional while the other three degenerate.
