How are lungs adapted for gas exchange gcse
WebHow are leaves adapted for gas exchange? Leaves have a large surface area, which means more space to allow CO2 to enter. They are thin so there is less for gases to travel. Leaves contain Stomata; these are small holes found distributed throughout the leaf which open and close, allowing gas exchange. Cells are organised in layers within the leaf.
