Microsporogenesis: Anther Development and Meiosis

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.

Microsporogenesis is the process of forming microspores in an anther. Learn about the meiotic divisions, ploidy, and development of microspore tetrads in this quiz.
