Question

What is microsporogenesis?explain the development of male gametophyte?

Answer 1

microsporogenesis is a good just formation of microscope from microspore Mother cell how the development of male gametophyte takes place so it develops from microscope mother cell microscope mother cell is just a differentiated cells of sporogenous tissue in antelope first of all microscope mother cell undergoes meiosis and form four haploid cell tetrad here refers to 4 haploid cells and each of the cell grows into a male gametophyte which is a pollen grain

Answer 2

Answer :-

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

• The pollen grains is the first cell of male gametophyte.

• Its nucleus divides into a large vegetative cell and a small generative cell.

• Vegetative cell is called tube cell and its nucleus is called tube nucleus.

• The generative cell flots in the tube cell.

• The entire structure of pollen grain is referred to as male gametophyte.

• In most of angiosperms the pollen grains are liberated at the two celled stage.
