Study Notes
Microsporogenesis
- In anther development, cells of the sporogenous tissue undergo meiotic divisions to form microspore tetrads, which are haploid (n) cells.
- Each cell of the sporogenous tissue is capable of giving rise to a microspore tetrad, making them potential pollen or microspore mother cells.
- Microsporogenesis is the process of formation of microspores from a pollen mother cell (PMC) through meiosis.
- Microspores are formed in a cluster of four cells, known as a microspore tetrad.
- As anthers mature and dehydrate, microspores dissociate from each other and develop into pollen grains.
- Inside each microsporangium, several thousand microspores or pollen grains are formed, which are released with the dehiscence of the anther.
