Question

embryo sac develops from megaspore mother cell through

a) 1 meiosis and 2 mitosis
b) 1 mitosis and 2 meiosis
c) 1 meiosis and 2 meiosis
d) 2 meiosis and 2 mitosis​

Answer 1

Answer:

1). From the remaining functional megaspore, the megagametophyte (also known as female gametophyte or embryo sac) develops by three mitotic divisions, at the mature stage consisting of 8 nuclei and 7 cells (one egg cell, two synergids, one central cell and three antipodals).

Answer 2

Answer:Your question is not clear.

Explanation:

Anyways, each megaspore mother cell is diploid which gives four haploid cell by undergoing meiosis. Out of tree,only one is functional which is megaspore. Later, it develops into embryosac.
