Question

Explain the development of male gametophyte in an angiosperm.

Answer 1

The male gametophyte in angiosperms develops within the pollen grain: 
1. Microspore Formation: Each microspore undergoes mitotic division to form a small generative cell and a larger vegetative cell. 
2. Mature Pollen Grain: The generative cell divides mitotically to produce two male gametes, resulting in a three-celled structure (two male gametes + one vegetative cell).
