Summary NCERT (Sexual reproduction in flowering plants class 12)
Sexual reproduction in flowering plants involves several key stages: Pollination: This is the transfer of pollen from the male part (anther) to the female part (stigma) of a flower. Pollination can occur through various agents, including insects, wind, water, or animals. Fertilization: After pollination, pollen germinates on the stigma and forms a pollen tube that grows down the style to the ovary. Sperm cells travel through this tube to fertilize the ovules, resulting in the formation of seeds. Seed Development: Fertilized ovules develop into seeds, and the ovary matures into a fruit that encloses the seeds. The fruit aids in the dispersal of seeds. Seed Dispersal: Seeds are dispersed by mechanisms such as wind, water, animals, or mechanical forces to spread the plant's offspring to new locations. Germination: When conditions are favorable, seeds germinate, and a new plant grows, continuing the cycle of reproduction. This process ensures genetic diversity and adaptation of flowering plants.
