Through the roots of the plant |
|
|
How is the surface area of roots increased? |
Root hairs |
|
|
How is the surface area of leaves increased? |

The stomata can close if the plant is losing water through evaporation faster than it is replaced by the roots |
|
|
How is the size of stomata controlled? |
By guard cells which surround the stomata |
