Question

What are the differences between the manner in which movement takes place in a sensitive plant and the movement of our legs?

Answer 1

1. The stimulus of touch causes the response in a sensitive plant Mimosa pudica. 

2. Droping of the leaves takes place due to change in osmotic pressure at the base of the leaf. 

3. When the stimulus is over, the osmotic pressure increases causing the leaf to become normal. 

4. This is not a growth related movement. 

5. It is not connected with the direction of the stimulus. 

6. Nerve messages in the form of electrical impulse reaches the leg muscles from the brain. 

7. On reaching the leg muscles, the muscles contract causing the movement of the leg.
