Seeds are the small parts produced by plants from which new plants grow.

A seed contains a miniature plant, called an embryo, that can develop into a fully grown plant. The outer shell of a seed, called a seed coat, protects the embryo. Inside the seed a nutritious material provides food to the embryo. In flowering plants this material is called endosperm.

The seed in a plant is the part that develops from the ovules after fertilization. They are enclosed in the fruit which develops from the fertilized ovary. The seeds are formed as a result of sexual reproduction and contain the young embryo which can develop into a new plant.

Seed Structure

The outer covering of a seed is called the seed coat. Seed coats help protect the embryo from injury and also from drying out. Seed coats can be thin and soft as in beans or thick and hard as in locust or coconut seeds. Endosperm, a temporary food supply, is packed around the embryo in the form of special leaves called cotyledons or seed leaves. These generally are the first parts visible when the seed germinates.

Germination

Germination is usually the growth of a plant contained within a seed; it results in the formation of the seedling. Under proper conditions, the seed begins to germinate and the embryo resumes growth, developing into a seedling.

All seeds need water, oxygen, and proper temperature in order to germinate. 

Seed Dispersal

Seed dispersal is the movement, spread or transport of seeds away from the parent plant. There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals.
