A seed is the part of a seed plant which can grow into a new plant. It is a reproductive structure which disperses, and can survive for some time. A typical seed includes three basic parts: (1) an embryo, (2) a supply of nutrients for the embryo, and (3) a seed coat.

The importance of seeds is biological and economic. They have large amounts of protein, starch, and oil, which are all important nutrients for the development of plants and humans. They are used in the production of many primary food sources for humans.
What is the importance of germination?
Seed germination determines continuous plant production necessary for human survival with regards to the supply of medicinal plants, feed for animal grazing, and food security. The propagation of some plants is only possible by seed, and if they are difficult to germinate, this threatens their continuous existence.
Which part develops into seeds?
After fertilization, each OVULE develops into seed and OVARY into a fruit. Each seed contains an undeveloped plane, embryo. The ovary surrounding the ovules develops into a fruit. Hence, the Ovule develops into a seed and the ovary into a fruit.

What is Germination?
- The seed coat splits.
- A tiny root grows downwards and a shoot grows upwards.
- This produces a seedling of a plant, which ultimately grows into a new plant.
- After some time, the plant bears flowers.
- All seeds can germinate when sown in moist soil under suitable conditions to produce new plants.
