Detailed explanation-1: -sensitive plant, (Mimosa pudica), also called humble plant, plant in the pea family (Fabaceae) that responds to touch and other stimulation by rapidly closing its leaves and drooping. Native to South and Central America, the plant is a widespread weed in tropical regions and has naturalized elsewhere in warm areas.

Detailed explanation-2: -When we touch Mimosa pudica (touch me not ), our touch acts as a stimulus for the plant and it closes its leaves in return. Some chemicals are released from the stem when we touch the plant. These chemicals force water to move out of the cell leading to the loss of turgor pressure. As a result, leaves droop.

Detailed explanation-3: -Mimosa pudica is the scientific name of sensitive plant.

Detailed explanation-4: -The sensitive plant, Mimosa pudica, is so-called because of its unique feature – when the plant is touched, the feathery leaves fold up and the stems droop. Also known as the mimosa plant, it’s thought that in the wild, this is a defence against being eaten by herbivores.

Detailed explanation-5: -Answer. The mimosa plant responds to stimuli like touch and heat by rapidly folding up its leaflets and drooping. It also exhibits the same reaction in response to light/dark cycles, folding up and drooping at night and reopening in the daytime. The leaves of mimosa plants have joint-like structures called pulvini.
