Answer:
The process of formation and differentiation of microspore from microspore mother cell by reductional division is known as microsporogenesis. The fertile portion of the stamen is known as an anther. Each anther is usually made up of two lobes connected by a connective. In each anther, lobe contains to Pollen chambers place longitudinal. Each pollen chamber represents a microsporangium and is filled with a large number of pollen grains of microscopes. Cells from the wall of microsporangium. It consists of the layer of endothelium, 1-3 middle layers and a layer of tapetum.
The tapetum is the innermost layer of the wall. The cells are multinucleate and polyploid. Compound sporopollenin is secreted in the exine of microspore wall and it is the most resistant material known because it is not be harmed by any chemicals and it protects the pollen.
