How do air spaces between mesophyll cells provide an opportunity for water to evaporate?
They expose a large internal surface area from which water can evaporate.
How does water vapour reach the stomata from within a leaf?
It moves through the interconnected air spaces between mesophyll cells.
How do the number and size of open stomata affect water vapour loss from a leaf, when other conditions are similar?
More or larger open stomata allow a greater rate of water vapour loss.
