How is the movement of leaves of sensitive plant different from the movement of a shoot towards light?
The movements of the leaves of the sensitive plant are touch-sensitive and independent of growth known as thigmonasty. While the movement of the shoot towards light is growth-related and known as phototropism.
Thigmonasty is the non-directional movement of a plant part, such as leaves, in response to touch. The movement of plants, especially prevalent in sensitive plants, which is very quick and can be observed easily is Thigmonasty. On touching the leaves of the plant, they shut the leaves and droop. Mimosa pudica (Touch me not) folds its leaves and droops when touched.
A plant’s response to light is called phototropism. Phototropism occurs in plants when they respond to sunlight. Phototropism can also be defined as the growth of a plant stem in response to sunlight. The stems of plants respond to sunlight by growing towards it. The plants also turn their leaves to face the sun. This enables their leaves to get as much sunlight as possible that is required for photosynthesis.
