Water moves from a leaf vein into mesophyll cells before leaving the leaf.
Which sequence describes the next stages of this movement?
diffusion through stomata, then evaporation from cell surfaces
active transport through stomata, then osmosis from cell surfaces
osmosis from cell surfaces, then active transport through stomata
evaporation from cell surfaces, then diffusion through stomata
