A seed is an important part of a flowering plant, as it gives rise to a new plant and is also essential in the life cycle of flowering plants. Some of the seeds are also used as food.
What is a seed?
A seed can be defined as a tiny, embryonic plant, enclosed in a protective layer called the seed coat, which usually with some stored food. The main parts of a seed are seed coat, endosperm and an embryo.

What is a radicle?
Radicle is a small embryonic root of the plant. It is a part of the seedling, which rises first from the seed during the process of seed germination.
What is plumule?
Plumule is the part of the seed embryo that grows into a shoot after the process of seed germination. It is a small portion of the plant, with a bud-like structure, giving rise to the first true leaves and is grown into a plant giving rise to several leaves, branches, flowers, and seeds.
