उत्तर
The leaves of a plant have tiny pores called stomata. The oxygen from air diffuses into a leaf through stomata and reaches all the cells, where it is used in respiration. The carbon dioxide gas that is produced during respiration, diffuses out from the leaf into the air through the same stomata.
