Question

How many pollen mother cells should undergo meiotic division to produce 64 pollen grains?
A.4
B.8
C.16
D.32

Answer 1

Hint: A tetrad haploid microspores are formed from one pollen mother cell during the meiotic division.

Complete step by step answer:
During the meiotic division, each pollen mother cell gives rise to four haploid pollen grains. Thus, to produce 64 pollen grains the 16 pollen mother cells are required. Few of the spores develop into female gametophytes or megagametophytes. The embryo sac is referred to as the female gametophyte and the megasporangium is known as the nucellus. Magagametogenesis is defined as the process of the development of megaspores into megagametophytes.

Hence, the correct option is (C) 16.

Additional information:
 Depending upon the pattern of occurrence of megasporogenesis the process of megasporogenesis varies from one species to another. In the case of a monosporic pattern, the single nucleus undergoes mitosis three times, producing an eight-nucleate cell. These eight nuclei are arranged into two groups of four.

Note:
A megaspore mother cell, or megasporocyte, is a diploid cell in plants in which meiosis will occur, resulting in the production of four haploid megaspores.
