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.

Detailed explanation-2: -A plant can’t flee threats, unlike mobile organisms. Instead, they have a highly sensitive threat-response system-like a plant’s version of an immune system. Prior research has suggested that touch could actually be beneficial, because it stimulates the plant immune system.

Detailed explanation-3: -Certain plants like Mimosa pudica (touch me not ), our touch acts as stimulus for 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.
