Question

What is the difference between the manner in which movement takes place in a sensitive plant and the movement in our legs ??biology class 10 cbse

Answer 1

⚫Movement in sensitive plant-
1) It occurs in response to an external stimulus like touch.

2) Plant cells change their shape by changing the amount of water in them.

3) No nerves are involved.

⚫Movement in Legs-
1) It is a voluntary action performed and controlled by our will.

2) Movement of legs (voluntary action) is controlled by cerebellum, a part of hindbrain. It is due to change in special proteins of muscles.

3) Nerves carry the message for movement of legs.

Answer 2

Movement in a plant,

Pants doesn't always move in the direction of stimulus and the movement is due to hormones secreted by the plant which it uses to protect itself.....if it is a sensitive plant.

Movement of our legs,

This movement is obviously due to command of our brain (cerebrum) , they move in a particular direction and instead of hormones here electrical impulses send signals to the muscles to move so it is comparatively quicker.

Hope it helps..
