Difference between Radicle and Plumule
Features |
Radicle |
Plumule |
---|---|---|
Location |
Found within the seed, at the tip of Hypocotyl |
Found in the seedling, at the tip of Epicotyl |
Development |
Serves as the embryonic root and develops in the root system of the plant |
Acts as the embryonic shoot develops into stem, leaves, and aerial parts of the plant |
Timing of emergence | It is the first structure to develop when the seed germinates | It develops after the radicle |
Function | The function of the radicle is to anchor the plant into the ground and absorb water and nutrients from the soil | The function of the plumule is to perform photosynthesis, as the leaves produced by the plumule capture sunlight and convert it into energy. |

Difference Between Radicle and Plumule
The Radicle and Plumule are two components of a plant’s embryo that play important roles in the growth and development of a plant. The major difference between these two is that Radicle develops into the root while Plumule develops into the shoot. The radicle serves as the embryonic root and is responsible for anchoring the plant and absorbing water and nutrients from the soil, while the plumule acts as the embryonic shoot, giving rise to the stem, leaves, and aerial parts of the plant which help in photosynthesis. Understanding the differences between radicle and plumule helps us to understand the complex processes involved in the earlier stages of plant development.
