HORTICULTURE

Detailed explanation-1: -Flowering plants reproduce sexually through a process called pollination. Flowers contain male sex organs called stamens and female sex organs called pistils. The anther is the part of the stamen that contains pollen. Pollen contains the male gametes.

Detailed explanation-2: -In angiosperms, pollination is the transfer of pollen from an anther to a stigma. Many plants can both self-pollinate and cross-pollinate. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant.

Detailed explanation-3: -In self-pollination, pollen grains are transferred from the anther to the stigma of the same flower. In cross-pollination, pollen grains are transferred from the anther of one flower to the stigma of another flower of the same kind. Pollination takes place in plants with the help of wind, water and insects.

Detailed explanation-4: -Pollination is the transfer of pollen grains from an anther to a stigma. Pollen can be transferred by an animal or by the wind. Fertilisation takes place inside the ovary when the nucleus of pollen grain fuses with the nucleus of an ovule to produce a zygote.

Detailed explanation-5: -Plants reproduce through two modes of reproduction: Asexual mode of reproduction – New plants arise from vegetative parts. Sexual mode of reproduction – New parts arise from reproductive parts of the plant.
