Detailed explanation-1: -Microspore is another name for pollen grain. Pollen grains are found in the male structures of blooming plants. Pollen grains are small structures that contain androecium, a flower’s male reproductive organ.

Detailed explanation-2: -Stamens: Male Reproductive Organs A stamen consists of an anther (which produces pollen, the male reproductive cell) and a filament.

Detailed explanation-3: -In flowering plants, the pollen grain is called a male gametophyte and the embryo sac is called a female gametophyte. Pollen grains develops within the anther and consists of two sperm cells (male gametes) encased within a vegetative cell. Hence Pollen grains are male gametophytes.

Detailed explanation-4: -Pollen is the fine, powdery substance released by anthers, a part of the flower. Pollen grains contain the male gametes of plants, which makes male sperm the closest analogous type of cell to pollen in the human body.
