Question

Which of the following is not correct?

• A. The megaspore mother cell is differentiated from one of the cells of the nucellus.
• B. The megaspore mother cell divides meiotically to form four megaspores.
• C. One of the megaspores enclosed within the megasporangium develops into a multicellular female gametophyte.
• D. The multicellular female gametophyte is not retained within the megasporangium

Answer 1

Answer: (D)

In plants, the diploid megaspore mother cell is differentiated from one of the cells of the nucellus by the process of megasporogenesis. This diploid mother cell undergoes meiosis to form four haploid megaspores from which one of the megaspores remains enclosed within the megasporangium and develop into a multicellular female gametophyte that is retained within the megasporangium.
