Q. Name the parts of an angiosperm flower in which development of male and female gametophyte take place.

Answer

Pollen grains represent the male gametophyte in an angiosperm which develops inside the microsporangia. On the other hand, female gametophytes of angiosperms are formed from the megaspore through the process of reduction division which lies inside the nucellus of ovule.

Q. What is meant by monosporic development of female gametophyte?

Answer

In the process of megasporogenesis, one megaspore mother cell divides by mitotic division to produce four megaspores. In many angiosperms one megaspore develops into female gametophyte and rest of the three get degenerate. This is termed monosporic development of female gametophyte.
