Question

The sensitive plant shows movement of leaves in response to touch. Explain such movement briefly.

Accepted Answer

Touch triggers electrochemical signals that cause water loss from pulvini cells, lowering turgor pressure and drooping leaves.. - The movement of leaves in the sensitive plant (*Mimosa pudica*) in response to touch is a nastic (non-directional) movement. - When touched, plants use electrical-chemical means to convey information from cell to cell. - Plant cells change shape by changing the amount of water in them (turgor pressure changes). - Water moves out of the cells at the base of leaflets (pulvini), making them flaccid and causing the leaves to fold up and droop.
