Biology Revision Notes For Class 12 Chapter 2 Sexual Reproduction in Flowering Plants

Flowers are the sexual reproductive organs in plants. They are the result of 125 million years of evolution. Today, there are nearly 400,000 species of plants, out of which, 94 per cent are flowering plants. They have dedicated reproductive structures that are grouped into male (Androecium) and female (Gynoecium) parts.

Apart from these structures, flowering plants need external aid to carry the pollen and ovules from place to place. These may include wind, water, insects and other animals.
