OBJECTIVE FORESTRY

Detailed explanation-1: -Pollen grains are the male sex cell of a plant. They are present in the anther of a flower.

Detailed explanation-2: -These sex cells are also called reproductive cells or gametes. Sperm cells are produced in men’s testicles and egg cells are produced in women’s ovaries.

Detailed explanation-3: -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. Male reproductive cells travel down the tube and join with the ovule, fertilizing it.
