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?
A) 2 Meiosis and 3 Mitosis
B) 1 Meiosis and 2 Mitosis
C) 1 Meiosis and 3 Mitosis
D) No Meiosis and 2 Mitosis
Explanation
[Solution by Claude - not from source] One meiosis of the megaspore mother cell gives four megaspores. The functional megaspore then undergoes three mitotic divisions to form the 8-nucleate, 7-celled embryo sac. Answer (3), as in the answer key.
