Plant organs include roots, stems and leaves.
The structure of a leaf has adaptations so that it can carry out photosynthesis effectively.
A leaf needs:
|Large surface area||Maximise light absorption|
|Thin||Short distance for carbon dioxide to diffuse into leaf cells|
|Thin waxy cuticle||Protects the leaves without blocking out light|
|Thin transparent epidermis||Allows light to reach the palisade mesophyll cells|
