Where the pollengrains are develop in anther during microsporogenesis?

Explanation

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 tetrade.
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 adn dehydrate the microspores dissociate from each other the develop into pollen grains. Inside each microsporangium several thousands of microspores or pollen grains are formed that are released with the dehiscence of anther
