After fertilization, the seed coat of the seed develops from

• A) Integuments
• B) Embryo sac
• C) Chalaza
• D) Ovule

The seed coat of a seed develops from the integuments. During the fertilization process, the integuments of the ovule grow and harden to form the protective outer layer of the seed. This layer plays a crucial role in safeguarding the seed as it develops and eventually germinates.

Key Terms

• Integuments: The protective layers surrounding the ovule that become the seed coat.
• Embryo sac: The female gametophyte that contains the egg cell and other cells involved in fertilization.
• Chalaza: The part of the ovule where the integuments are attached, but it does not form the seed coat.
• Ovule: The structure that develops into a seed after fertilization.

Importance of the Seed Coat

The seed coat serves several important functions, including protecting the embryo and providing a barrier against pathogens and environmental factors. It also helps in the regulation of water absorption during germination.
