Question

.The leaves of the Mimosa plant droop when touched. Give reason

Answer 1

Explanation:

It is due to turgor pressure difference between the upper and lower halves of the base of petiole (pulvinus). Lower half cells lose water and upper half cells of pulvinus become turgid due to transfer of water from lower cells. Thus, the entire leaf droops down when touched.

Answer 2

Answer:

Explanation:

When we touch Mimosa pudica (touch me not ), our touch acts as stimulus for plant and it closes its leaves in return. Some chemicals are released from the stem when we touch the plant. These chemicals force water to move out of the cell leading to the loss of turgor pressure.so touch me not droop down on touching.
