Seed
A seed is the small, embryonic plant enclosed in a covering called the seed coat. It is the product of sexual reproduction in plants and contains the genetic information necessary for the growth and development of a new plant.
Parts of a Seed
A typical seed consists of the following parts:
- Seed Coat: The outer protective covering of the seed.
- Embryo: The young, undeveloped plant inside the seed.
- Cotyledon: The seed leaf that provides nutrients to the developing plant.
- Endosperm: The tissue that provides food for the embryo.
Seed Germination
When conditions are right, a seed undergoes germination, a process in which the embryo begins to grow and develop into a new plant. The key factors for seed germination include water, oxygen, and the right temperature.
Study Guide
- What is a seed and what does it contain?

- Explain the process of seed germination and the factors involved.
- Why is the seed coat important for the seed?
- How do seeds disperse in nature?

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
