The Key Components of Seeds and Their Functions

The video explains the structure of seeds, highlighting their importance in plant reproduction. It details the three main parts of a seed: the seed coat, endosperm, and embryo. The seed coat protects the seed, the endosperm provides nutrition, and the embryo contains the essential components for plant growth. Examples like almonds illustrate these concepts. The video also discusses the roles of cotyledons in seeds with and without endosperm.
