Question

Characteristic three successive free nuclear mitotic divisions are involved in the development of __________ in angiosperms.

• A. female gametophyte
• B. embryo
• C. male gametophyte
• D. endosperm

Hint:

Three mitotic divisions produce 8 nuclei in the embryo sac.

Answer 1

The Correct Option is A

Step 1: Understanding megagametogenesis.
In angiosperms, the female gametophyte develops from a functional megaspore through successive mitotic divisions.
Step 2: Nuclear divisions involved.
Three free nuclear mitotic divisions produce an eight-nucleate embryo sac, which later organizes into the female gametophyte.
Step 3: Conclusion.
Thus, the correct answer is (A) female gametophyte.
