Question

why does touch me not plant closes after a touch​

Answer 1

Answer:

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.

hope you find it helpful :)
