Answer 1

Answer:

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). ... When the guard cells lose turgor, the elastic inner walls regain their original shape and the stoma closes.Plants obtain the gases they need through their leaves. ... The gases diffuse into the intercellular spaces of the leaf through pores, which are normally on the underside of the leaf - stomata.
