Detailed explanation-1: -The ovules develop into seeds, from which new plants will grow. In most angiosperms, part of the flower develops into fruit, which protects the seeds inside them.

Detailed explanation-2: -Hence, Seed coat, endosperm, and embryo are the three components of a plant seed. The seed coat protects the seed from harm caused by physical, mechanical, temperature, and water.

Detailed explanation-3: -Seed coat is the outer covering of the seed which protects the internal parts of the seed.

Detailed explanation-4: -An ovule is a structure inside the flower’s ovary. The plant’s ovary is the structure that contains the seed(s). The ovary develops into a fruit to protect the seed(s). Some fruits have only one seed because the ovary has only one ovule. Some fruits have multiple seeds because the ovary contains multiple ovules.
