Answer 1

Ovules generally differentiate a single megaspore mother cell (MMC) in the micropylar region of the nucellus. ... Only the functional megaspore develops into the female gametophyte (embryo sac). This method of embryo sac formation from a single megaspore is termed monosporic development.

Answer 2

Hey Dear,

◆ Explanation -

• Megasporogenesis is the process of formation of megaspores in ovules of angiosperms.
• Each ovule (lot in a ovary) contains a megaspotocyte known as megaspore mother cell.
• This megaspore mother cell is formed at micropylar region & is dilpoid in number.
• Megaspore mother cell undergoes meiotic cell division to produce four halpoid megaspores.
• Out of these only one female gametophyte survives till maturity & fertlizes with sperm.
