Answer 2

Movement in a sensitive plant:

1. There is no specialised tissue in plants for conduction of information.

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

3.Plant cells do not have specialised proteins.

1.There is a specialised nervous tissue in animals for conduction of information and muscle cells to help on movement.

2. Muscle cells contract or relax to effect movement.

3. Muscle cells have specialised protein which help muscles to contract or relax....
