Detailed explanation-1: -As mentioned above, a seed contains the embryo of the new plant, with a supply of food for the embryo until it has formed sufficient roots and leaves to obtain its own food. The embryo is a miniature plant in a state of arrested development.
Detailed explanation-2: -A seed contains a miniature plant, called an embryo, that can develop into a fully grown plant. The outer shell of a seed, called a seed coat, protects the embryo. Inside the seed a nutritious material provides food to the embryo. In flowering plants this material is called endosperm.
Detailed explanation-3: -The embryo is the most important part of a seed.
Detailed explanation-4: -Seeds contain stored food in the cotyledons to provide energy and materials for growth. This is usually in the form of starch – a large, insoluble molecule (long chain of glucose), that keeps the food immobile.
