Question

In majority of angiosperms -

• A. egg has a filiform apparatus
• B. there are numerous antipodal cells
• C. reduction division occurs in the megaspore mother cells
• D. a small central cell is present in the embryo sac

Answer 1

The Correct Option is C

Answer: \(\boxed{\text{Reduction division occurs in the megaspore mother cells}}\) 

Explanation:
 

• In most angiosperms, the development of the female gametophyte (embryo sac) begins when the megaspore mother cell (MMC) undergoes meiosis (reduction division).
• This meiosis results in the formation of four haploid megaspores, out of which usually only one is functional and develops into the embryo sac.
• This is a characteristic process of sexual reproduction in flowering plants (angiosperms).

Why the other options are incorrect:

• Option 1: The synergids, not the egg cell, possess a filiform apparatus.
• Option 2: Typically, there are only three antipodal cells in the embryo sac of angiosperms.
• Option 4: The central cell is large, not small, and contains two polar nuclei.
