Solution

Pollen grains are formed by meiotic division in locules of anthers.

Explanation:

Pollen grains are formed inside the locules (pollen sacs) of the anther. The diploid microspore mother cells (PMCs) present in the locules undergo meiotic division to produce haploid microspores. These microspores further develop into pollen grains.
