Oleander (Nerium oleander) is another plant that has specifically adapted to survive drought conditions, possibly native to the Mediterranean though its precise origin is unknown. The stomata is a structure in a plant cell that allows water or gases to be let into the plant. A third gas, water vapor ($\ce{H2O}$), also escapes through the stomata, though this has both beneficial and detrimental effects for the plant. CLOSED STOMATA- Stomata must be open for the plant to photosynthesize; however, open stomata present a risk of losing too much water through transpiration. Scope: (Page-70) Question 1.
