Question

Explain the process of megasporogenesis in angiosperms 2

Answer 1

hi mate.

thankx for asking this question.

here is your answer,


$megasporogenesis =$



The process of formation of the

megaspore from the megaspore mother cell is

called megasporogenesis. Ovules generally

differentiate in to a single megaspore mother

cell in the micropylar region of the necellus,

One maaspore is functional, while the other

three degenerate. Only the functional

megaspore develops into the female

gametophyte.


The nucleus of the functional

megaspore divides mitotically to form two

nuclei, which move to opposite poles, forming

2-nucleate embryo sac.Two more sequential

mitotic nuclear divisions result in the formation

of the 4 nuclei and the later 8-nucleate stage

of the embryo sac.





Thank you.
