Describe the process of Microsporogenesis.
When the anther is young, a group of compactly arranged homogenous cells called the sporogenous tissue occupies the centre of each microsporangium.
As the anther develops, the cells of the sporogenous tissue undergo meiotic divisions to form microspore tetrads.
As each cell of the sporogenous tissue is capable of giving rise to a microspore tetrad.
- Each one is a potential pollen or microspore mother cell.
The process of formation of microspores from a pollen mother cell through meiosis is called microsporogenesis.
The microspores as they are formed, are arranged in a cluster of four cells is the microspore tetrad.
As the anthers mature and dehydrate the microspores dissociate and dehydrate the microspores dissociate from each other and develop into pollen grains.
Inside each microsporangium several thousands of microspores or pollen grains are formed that are released with the dehiscence of anther.

Tapetal cells are characterized by
The microspore tetrad of angiosperm at the time of formation, are surrounded by a callose wall. Breakdown of this wall is brought about by the enzyme callase synthesized by the
