Movement in sensitive plants | Movement in our legs | ||
|---|---|---|---|
1. | The movement that takes place in a sensitive plant such as Mimosa pudica occurs in response to touch (stimulus). | 1. | Movement in our legs is an example of voluntary actions. |
2. | For this movement, the information is transmitted from cell to cell by electrochemical signals as plants do not have any specialized 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. | 3. | In animal muscle cells, some proteins are found which allow the movement to occur. |
Leaves of the sensitive plant move very quickly in response to ‘touch’. How is this stimulus of touch communicated and explain how the movement takes place?
