Leaves are adapted for photosynthesis and gaseous exchange. They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out.
The adaptations of leaf for photosynthesis are as follows :-
➤ Leaves provide large surface area for maximum light absorption. Which help them to absorb more photons.
➤ Leaves are arranged at right angles to the light source in a way that causes overlapping for absorption of more light.
➤ The extensive network of veins enables quick transport of substances to and from the mesophyll cells.
➤ The presence of numerous stomata for gaseous exchange, which helps them to absorb more CO2.
➤ The chloroplasts are more in number on the upper surface of leaves, as more light exposure on the upper surface.
