The structure of seed is as follows- 1. The outer layer of seed is called coat which is covering of the seed. 2. The seed contains baby plant inside, called as an embryo. 3. Seed stores reserved food in fleshy Cotyledons.

There are two types of reproduction: 1.Reproduction through seeds 2.Reproduction through different parts of plants such as leaf, roots, stems.

When pollination is successful, the pollen joins the egg present in the ovary and become a seed. This is called fertilisation. After fertilisation, the ovary swells and changes into fruit.
18.
The process by which seed grows into seedling is called germination. The seed requires oxygen, water and minimum temperature for germination.

Rose, lemon, jasmine

Reproduction in plants through seeds involves below steps- 1. Pollination- The transfer of pollen from a flower to the stigma of the same flower or of another flower. It is done by pollinating agents such as insects, wind, water and animals. 2. Fertilisation- When pollination is successful, the pollen joins the egg present in the ovary and become a seed. This is called fertilisation. 3. Seed formation 4. Dispersal of seeds 5. Germination- The process by which seed grows into seedling is called germination.
