It is the “engine” that pulls water up from the roots to: 1. supply photosynthesis (1%-2% of the total); 2. bring minerals from the roots for biosynthesis within the leaf; 3, cool the leaf. The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma). Each stoma can be open or closed, depending on how turgid its guard cells are. Stomata control a tradeoff for the plant: they allow carbon dioxide in, but they also let precious water escape.
