Study Notes
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:
- Seed Coat: The outer protective layer of the seed.
- Embryo: The tiny plant inside the seed that will grow into a new plant.
- Endosperm: The food supply for the growing embryo.
Parts of the Embryo:
- Radicle (Root): The part of the embryo that will grow into the roots of the new plant.
- Cotyledon (Seed Leaf): The part of the embryo that will grow into the first leaves of the new plant.
- 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:
- Germination: When a seed starts to grow and sprout.
- Seedling: The young plant that grows from a seed.
- Maturation: When the seedling grows into a mature plant.
