Differences Between Radicle and Plumule

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.

Radicle and Plumule – Differences

It is the embryonic root of the plant. It is the embryonic shoot of the plant.
Direction of Growing
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 produces food by the process of photosynthesis.
