Question

How have you identified radical and plumule

Answer 1

Radical is a part of plant from which the root system of a plant grows

From the plumule the shoot system of the plant grows

To identify whether the part is a radical or plumule, place the seed in a petri dish. Keep the dish near the window. The part which grows towards the sunlight is plumule.

Pour some water in the dish and observe.Radical grows towards the direction of water whereas plumule will grow towards the direction of light.Hence we can easily identify the radical.
