Question

Mimosa (touch me not plant) shows

• A. Thigmotropism movement
• B. Chemotactic movement
• C. Seismonasty
• D. None of the above

Answer 1

The correct option is C Seismonasty

A response of a plant, that causes movement independent of the direction of the stimulus is a nastic response. It is not a growth response, is reversible, and can be repeated many times.

Seismonasty is a nastic movement in response to shock, especially the rapid folding of the leaflets of the sensitive plant due to changes in turgor pressure, caused by vibration, example- Mimosa pudica.
