The seed is made up of which of the following parts?

The seed is comprised of three main parts: the seed coat, the cotyledon, and the embryo.

The seed coat serves as a protective outer layer that safeguards the seed from environmental factors, such as moisture loss and external pathogens.

The cotyledon is a significant part of the seed that provides nutrients to the developing plant during germination before the true leaves appear.

The embryo is the essential part of the seed that develops into the new plant. It contains the beginnings of the root and stem, as well as the first leaves (or cotyledons).

Since all these components—the seed coat, cotyledon, and embryo—are integral to the structure and function of a seed, the comprehensive option including all these parts is indeed the correct choice. The seed’s successful development into a new plant relies on the functionality of each of these components working in conjunction.
