Define the terms pollination and fertilization. Draw a diagram of a pistil showing pollen tube growth into the ovule and label the following: pollen grain, male gamete, female gamete and ovary.

Pollination is the process where pollen grains are transferred from the male anther of a flower to the female stigma, for the fertilization and production of seeds.

Pollination is done either by biotic agents like insects, birds, and bats or by abiotic agents like wind and water.

Fertilization is the process in which the nuclei of the female gamete and male gamete unite together in the ovary of the flower to form a diploid zygote.
