Question

9. Spongy mesophylls in leaves bring up water to the leaves for use in making food. Do the leaves use up all the water? What happens to the water left over?

Answer 1

Transpiration. When the plant opens its stomata to let in carbon dioxide, water on the surface of the cells of thespongy mesophyll and palisademesophyll evaporates and diffuses outof the leaf. ... Water is drawn from the cells in the xylem to replace that which has been lost from the leaves.
