How many of the daughter cells obtained from a megaspore mother cell result in the matured ovum?
Options
(a) four

(c) two
(d) one
Correct Answer:
one
Explanation:

Generally, 3 megaspores towards micropylar end degenerate and 4th towards chalazal end remains as the functional megaspore which develops into embryo sac. One mature ovum is formed per embryo sac.
