  • What is a seed coat?

  • The seed coat is one of three parts of a seed, in addition to the endosperm, or the food storage area of the seed, as well as the plant embryo. Seed coats on alfalfa, radish, and lettuce seeds or beans happen to be dark, while the coats on corn, peas, and squash tend to be light. Are you a student or a teacher?

  • How does the seed coat maintain dormancy?

  • By regulating the amount of water entering and leaving the seed, as well as gas exchange, the seed coat maintains the embryo in a napping state called dormancy. Dormancy is only broken when the seed’s environment has adequate temperature, water, and gas exchange to promote growth.

  • What is the function of the outer layer of a seed?

  • The outer layer is thick and known as the testa. The inner layer is thin and known as tegmen. A thick seed coat protects the seed from sunlight and water. It prevents the loss of water and entry of parasites within the seeds.

  • What is the function of the endosperm of a seed?

  • The endosperm is the food storage area of the seed. The purpose of the seed coat is to protect the seed from physical, temperature-related, or water damage. The seed coat also ensures that the plant seed remain in a state of dormancy until conditions are right for the plant embryo to germinate, or sprout.
