Question

Explain how movements of leaves of a sensitive plant different from movements of shoots toward light

Answer 1

The movement of leaves of thesensitive plant, Mimosa pudica or “touch me not”, occurs in response totouch or contact stimuli. Thismovement is independent of growth. The movement of shoot towards lightis known as phototropism. This type ofmovement is directional and is growth dependent.

Movements in Mimosa pudica (touch sensitive plant) occur in response to touch.

In such movements, plant cells change shape by changing the amount or water in them resulting in folding up and drooping of leaves.

This phenomenon is called thigmonasty and it is a movement independent of growth. When plants respond to a stumuli by growing in a particular direction is movement due to growth.

This growth is directional. Movement of shoots toward light indicates phototropism, i.e. movement occurs in response to light.
