Question

why mimosa pudica leaves drop down when touche​

Answer 1

｡.Explanation :

● When touched, this sensitive leaf 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 (via the pulvinus) which then becomes flaccid. This causes the leaves to close.

Answer 2

Mimosa pudics leaves are very sensitive. If we think where exactly the plant is touched and what part of the plant actually moves, it is apparent that movement happens at a point different from the point of touch. So, information that a touch has occured is communicated and as a result they drop down.
