Sexual Reproduction in Flowering Plants

During microsporogenesis meiosis occurs in
A. Endothecium
B. Microspore mother cells
C. Microspore tetrads
D. Pollen grains

B. Microspore mother cells

The process of formation of microspore from a pollen mother cell by meiosis is called microsporogenesis.
Each cell of the sporogenous tissue in a microsporangium acts as a potential pollen mother cell (PMC) or microspore mother cell.
PMC undergoes meiotic divisions to form cluster of four cells called microspore tetrad.
On maturity, the anther dehydrates and the microspores separate from each other to form pollen grains.
