HORTICULTURE

Detailed explanation-1: -In order to make more plants, pollen must move from the male part of a flower to the female part of a flower, and then the pollen tube must grow to the ovary to make a seed. Pollination is the process by which pollen is moved from the male part of a plant to the female part of a plant.

Detailed explanation-2: -In flowering plants, however, the ovules are contained within a hollow organ called the pistil, and the pollen is deposited on the pistil’s receptive surface, the stigma. There the pollen germinates and gives rise to a pollen tube, which grows down through the pistil toward one of the ovules in its base.

Detailed explanation-3: -Pollen grains are created through the process of meiosis, during which cells divide and grow in number. The grains of pollen are often located in pollen sacs on the ends of the stamen (the male parts of the flower), which typically surround the carpel (the female parts of the flower).
