How are leaves of a plant adapted to enable photosynthesis?

Leaves have 4 main adaptations which enable them to carry out photosynthesis successfully. 

1) Thin - this allows carbon dioxide to easily diffuse into the leaf cells 

2) Transparent epidermis - this allows light to reach the palisade cells 

3) Large surface area - allows lots of light to be absorbed 

4) Waxy surface - protects the leaves without blocking out light
