Observe the diagram



i) Mention the type of movements shown in figure A and B.

ii) How does this movement differ from the movement of mimosa?

(i) A is geotropism as the roots are moving in the direction of gravity. And B is phototropism as shoots are growing towards the light stimulus. Therefore, this movement is dependent on growth.

(ii) In mimosa leaves show movement on touch that is when their leaves are touched they curl up. So, in case of mimosa leaves show movement whereas in geotropism roots or shoot shows movement. Therefore, in this case, a movement is independent of growth.
