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 the 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 shoot plant giving rise to several leaves, branches, flowers, and seeds.

Radicle and Plumule – Differences
| It is the embryonic root of the plant. | It is the embryonic shoot of the plant. |
| It grows downwards into the soil. | It grows upwards into the air. |
| It is whitish in colour. | It is less whitish in colour. |
| It is the first part of the seedling. | It grows after the radicle. |
| It develops into the root. | It develops into the shoot. |
| It is negatively phototrophic. | It is positively phototrophic. |
| It is positively geotropic. | It is negatively geotropic. |
| It is positively hydrotropic. | It is negatively hydrotropic. |
| It absorbs water and minerals from the soil. It also fix the plant rigidly into the soil. | It produces food by the process of photosynthesis. It is the visible part of plant that produces leaves, branches, buds, flowers, fruits and seeds. |
