Structure of Seeds

What is a Seed? A seed is a tiny plant that is enclosed in a protective covering. It has all the parts needed to grow into a new plant.

Three Main Parts of a Seed:

1. Seed Coat: The outer protective layer of the seed.
2. Embryo: The tiny plant inside the seed that will grow into a new plant.
3. Endosperm: The food supply for the growing embryo.

Parts of the Embryo:

1. Radicle (Root): The part of the embryo that will grow into the roots of the new plant.
2. Cotyledon (Seed Leaf): The part of the embryo that will grow into the first leaves of the new plant.
3. Hypocotyl (Stem): The part of the embryo that will grow into the stem of the new plant.

Fun Facts:

• Seeds can be different shapes and sizes depending on the type of plant.
• Some seeds can remain dormant for years before germinating.
• Seeds need the right amount of water, light, and temperature to grow into a new plant.

Seed Growth:

1. Germination: When a seed starts to grow and sprout.
2. Seedling: The young plant that grows from a seed.
3. Maturation: When the seedling grows into a mature plant.
