Biology revision- B2.1 transport

The uptake of water by a plant increases if a fan blows air over the leaves. This is because:

If a fan blows air over the leaves, the uptake of water by a plant increases because diffusion is faster when the diffusion gradient is greatest.

The loss of water vapour from leaves slows down if the plant is put into a plastic bag. This is because:

If the plant is put into a plastic bag, the loss of water vapour from leaves slows down because the humidity increases.
