Explanation

The Mimosa plant exhibits thigmonastic movement, which is a type of tactile or touch-induced movement.

When the Mimosa plant's leaves are touched or disturbed

They rapidly fold inward and droop, a phenomenon known as thigmonastic movement or thigmonasty.

This response is thought to be a defense mechanism against herbivores or other threats.

The movement is not due to changes in turgor pressure or growth

But is instead a rapid reversible response to mechanical stimulation.
