Microsporogenesis and Pollen Formation — NEET Biology
📚 Practice ConceptAs 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 (PMC) through meiosis is called microsporogenesis. The microspores, as they are formed, are arranged in a cluster of four cells–the microspore tetrad. As the anthers mature 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.
Assertion (A): Microsporogenesis is the process of male gamete formation in anthers. Reason (R): Microsporogenesis directly produces mature pollen grains from pollen mother cells.
