How the leaves adapted their function

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 cells inside the leaf have water on their surface.

large surface area, and to reduce the water loss, the leaves are coated in a waxy cuticle to stop the water vapour escaping through the epidermis. they also have a large surface area to absorb sunlight.

Explanation:

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%
