Describe the process of Microsporogenesis.

(N/A) $1$. When the anther is young,a group of compactly arranged homogenous cells called the sporogenous tissue occupies the centre of each microsporangium.
$2$. As the anther develops,the cells of the sporogenous tissue undergo meiotic divisions to form microspore tetrads.
$3$. Each cell of the sporogenous tissue is capable of giving rise to a microspore tetrad and acts as a potential pollen or microspore mother cell $(PMC)$.
$4$. The process of formation of microspores from a pollen mother cell through meiosis is called microsporogenesis.
$5$. The microspores,as they are formed,are arranged in a cluster of four cells called the microspore tetrad.
$6$. As the anthers mature and dehydrate,the microspores dissociate from each other and develop into pollen grains.
$7$. Inside each microsporangium,several thousands of microspores or pollen grains are formed that are released with the dehiscence of the anther.
