The sensitive plant detects touch through specialized cells that respond to mechanical stimulation. While lacking nervous and muscle tissue, it employs unique cellular mechanisms for touch sensitivity.

Plants show two different types of movement – one that is dependent on growth and the other that is independent of growth.

If the growth of a seedling is prevented, it will not show any movement. The directional movement of a seedling is caused by growth.

The key distinction lies in the fact that one type of plant movement is dependent on growth, while the other type is independent of growth.

The sensitive plant of the Mimosa family is referred to as “chhui-mui” or the “touch-me-not” plant.
