Which statement explains the effect that atmospheric humidity has on the rate of transpiration?
- AIn high humidity, the transpiration rate is high because there is slow diffusion of water vapour through stomata.
- BIn high humidity, the transpiration rate is low because there is rapid diffusion of water vapour through stomata.
- CIn low humidity, the transpiration rate is high because there is rapid diffusion of water vapour through stomata.
- DIn low humidity, the transpiration rate is low because there is slow diffusion of water vapour through stomata.
