Q.

How many meiotic and mitotic divisions need to occur for the development of a mature female gametophyte from the megaspore mother cell in an angiosperm plant?

  1. A

    No Meiosis and 2 Mitosis

  2. B

    2 Meiosis and 3 Mitosis

  3. C

    1 Meiosis and 2 Mitosis

  4. D

    1 Meiosis and 3 Mitosis

Solution

The megaspore mother cell (2n) undergoes 1 meiotic division producing 4 haploid megaspores; usually only one functional megaspore survives.

This functional megaspore then undergoes 3 successive mitotic divisions (free-nuclear) to yield 8 nuclei, which organize into the 7-celled, 8-nucleate mature female gametophyte (embryo sac) typical of angiosperms.

1 Meiosis + 3 Mitosis.
