Question

What is the difference between the manner in which movement takes place in a sensitive plant and the movement in our legs?

Answer 1

The movement of sentitive plants leaves due to the sudden loss of water in pad like swelling (called pulvinin) at the base of all the leaves. Pulvini limp gets drooped and folded due to the loss of water. On the other hand, the movement of our legs take place due to pull in the muscles of legs on the leg bones.
