How does the leaves of touch-me-not plants respond to touch?

How does a touch-me-not plant shows movement?

‘Touch me not’ plant shows seismonastic movement. The ‘touch me not’ plant (Mimosa pudica) is well known for its rapid plant movement. It undergoes changes in the orientation of leaf termed “sleep” or nyctinastic movement. The foliage (leaves) closes during the darkness and reopens in the light.

Why do the leaves of a sensitive plant close immediately when touched?

The leaves of the Mimosa achieve this rapid folding by a change in turgor pressure. When the leaves of the Mimosa are touched, there is a change in the concentration gradient of potassium and chloride ions within two types of cells, the flexor and extensor cells, within the pulvinus of the plant.

Many plants close up at night, usually to protect pollen or reduce water loss while the leaves aren’t photosynthesising.

Why do the leaves of a plant stay upright when touched?

It is due to turgor pressure that the leaves of this plant stay upright unless disturbed externally. Now, when you touch or shake the leaves (known as seismonastic movements), the swollen base of the leaf stalk (called the ‘pulvinus’), which contains certain contractile proteins, is activated.
