Class 12 Sexual Reproduction in Flowering Plants (Chapter – 1) by Tejashri CH (TH)

Description

Sexual reproduction in flowering plants involves the fusion of male and female gametes to produce seeds. It typically occurs through the process of pollination, fertilization, and seed formation.

1. Pollination: This is the transfer of pollen (male gametes) from the anther (male part) to the stigma (female part) of the flower. Pollination can be achieved by wind, water, or pollinators like insects, birds, or animals.

2. Fertilization: Once the pollen reaches the stigma, it travels down the style to the ovary, where it fertilizes the ovules (female gametes). This results in the formation of a zygote, which develops into a seed.

3. Seed Formation: The fertilized ovule becomes a seed, which contains the embryo plant. The ovary develops into a fruit, which protects the seeds and aids in their dispersal.

Sexual reproduction ensures genetic diversity, which helps plants adapt to changing environments.
