Question

Is the closing of leaves of a touch-me-not plant an example of thigmotropism??

Answer 1

Yes, it is an example of thigmotropism which is the tendency for a plant organ to bend in response to touch.

Answer 2

The touch me not plant is also called chhui mui. It belongs to the Mimosa family. When we touch them, they begin to fold up and droop. The leaves of this plant move very quickly in response to touch. There is no growth involved in this movement.
