| $2.$ | For this movement, the information is transmitted from cell to cell by electro- chemical signals as plants do not have any specialised tissue for conduction of impulses. | $2.$ | The signal or messages for these actions are passed to the brain and hence are consciously controlled. |
| $3.$ | For this movement to occur, the plant cells change shape by changing the amount of water in them. |
