Answer 2

Answer:

Coordination is the ability to use different parts of the plants together smoothly. There are 2 types of movements in plants:

1. Tropic movement:

In this movement growth depends in direction of stimulus.It is further divided:

1. Phototropic movement: Movement of stem towards sunlight.

2. Geotropic movement: Movement of root towards gravity.

3. Hydrotropic movement: Movement of root towards water.

4. Chemotrophic movement: Movement of pollen tube towards pollen grain.

5. Thigmotrophic movement:Movement of branches of creepers to some solid support.

2. Nastic Movement:

Growth does not depend on direction of stimulus.

1. Photonastic movement: Movement of sunflower towards light.

2. Thigmonastic movement: Drooping of 'touch me not' leaves on touching.
