Question

Question 14. Explain the mechanism of folding of leaves of Mimosa pudica in response to touch.​

Answer 1

Answer: When touched, the sensitive leaves of mimosa pudica reacts to stimulus as there is a higher pressure at that point and the water in the vacuoles of the cells of the leaf lose water to the adjacent cell. All the water escapes the leaf which then becomes flaccid. This causes the leaves to close.

Answer 2

When the Mimosa pudica, commonly known as the sensitive plant, is touched by another organism, its leaves fold in upon themselves and its stems droop. ... The leaves of the Mimosa achieve this rapid folding by a change in turgor pressure
