How many of the daughter cells obtained from a megaspore mother cell result in the matured ovum?
Options
(a) four
(b) three
(c) two
(d) one
Correct Answer:
one
Explanation:
The megaspore mother cell (2n) undergoes reduction division (meiosis) to form linear tetrad of four haploid megaspores by megasporogenesis. 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.
