    A leaf has several pores on its lower surface called stomata whose opening and closing is controlled by guard cells and help in exchange of gases and transpiration. It also has a green coloured plastid called chloroplast which stores chlorophyll and acts as the site for photosynthesis in green plants. It also has an epidermal layer which acts as a skin for a leaf as in animals and gaps in between to ensure proper movement of gases.
