Seed Structure and Function Concepts

The video tutorial explains the role of seeds in plant growth, highlighting their diverse sizes, shapes, and types. It describes the structure of seeds, including the embryo and seed coat, and their protective functions. An experiment with beans demonstrates water absorption and swelling. The video also covers seed germination, noting that seeds can remain dormant until conditions are favorable for growth.
