How are Leaves adapted?

Leaves need Carbon Dioxide for Photosynthesis and Oxygen for Respiration. Obviously when they are doing one of the two, the concentration will be higher outside which means diffsusion. Leaves makes it more quicker and easier. They are broad [larger surface area : volume] and are thin which makes the distance not far for the gases. They have air spaces inside it to let the gases to move at ease and also increases the ratio. Stomato at the bottom of the leave also lets the gases diffuse in/out They also allow water to escape [Transpiration]
