Detailed explanation-1: -Final answer: Pollen grains are produced in anther.

Detailed explanation-2: -Through the process of meiosis, pollen is formed in the pollen sacs (microsporangia) inside the anthers of a flower. The anther, while it is developing from anther primordium (undifferentiated cells), forms two clusters of cells.

Detailed explanation-3: -In angiosperms, pollen is produced by the anthers of the stamens in flowers. In gymnosperms, it is formed in the microsporophylls of the microstrobili (male pollen cones). Pollen consists of one or more vegetative cells and a reproductive cell.

Detailed explanation-4: -Pollen grains are the male gametes. These are formed in the anther sac, by meiosis cell division each microspore mother cells produces four microspores or pollen grains.

Detailed explanation-5: -The anther produces pollen (male reproductive cells). The filament holds the anther up. During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary.
