a.integument
b.nucellus
c.megaspore
d.megaspore mother cell

Answer 1

In the ovule, meiosis occurs in the megaspore mother cell.

What is megasporogenesis?

• During megasporogenesis,  an archesporium cell also known as a hypodermal cell becomes denser, expands in size, and its nucleus becomes larger and more prominent than before.
• The division of the archesporial cell, which is also called a megaspore mother cell, in crassinucellate ovules forms two types of cells: an inner primary sporogenous and an outer parietal cell.
• Both of these cells are referred to as megaspore mother cells. During meiosis, the megaspore mother cells divide into four haploid megaspore mother cells.
• Thus meiosis occurs in the megaspore mother cell during ovulation.
