Question

development of male or female gametophyte

Answer 1

Answer:

Explanation:

Development of Male Gametophyte

The development of pollen grains or microspores in the microsporangium of an anther is called microsporogenesis.

Each lobe contain an elongated microsporangium.

Within the four lobes, some of the hypodermal cells at each corner become differentiated to form archesporium.

Each archesporial cell divides to form a primary parietal cell to the epidermis and primary sporogenous cell to the inside.

The primary parietal cell divides to form wall of the anther.

The primary sporogenous cells divides repeatedly to form sporogenous tissue.
