Reproduction is the process by which plants and animals produce young ones and increase their number. Flowering plants have root, stem and leaves, called vegetative organs, and flowers, fruits and seeds, called reproductive organs. This chapter explains how a flower becomes a fruit with seeds through pollination and fertilization, the types of asexual reproduction, and the modifications of root, stem and leaves.
1. Reproduction in Plants
- When plants are reproduced from seeds, the process is called sexual reproduction.
- All other ways of reproduction without seed are called asexual reproduction.
- The drumstick tree can be grown from both seeds and stem cuttings.
- A potato plant grows from the stem tuber (a vegetative part), not from seed.
2. Parts of a Flower
Seed is produced from a flower by the process of pollination and fertilization; this is sexual reproduction. The flower is the reproductive organ of a plant and has four whorls.
