Leaf Area Surface Leaves Specialised Maximise Diffusion Flattened

Leaves are adapted for diffusion through their flattened shape, which maximizes surface area, and through internal air spaces that facilitate gas exchange.

Leaves are specialized for diffusion through their flattened shape, which increases surface area, and internal air spaces that enhance gas exchange.

Front How are leaves specialised to maximise diffusion?
Back
  • The flattened shape of the leaf increases the area of this exxchange surface so it's more effective
  • The air spaces inside the leaf increase the area of this surface so there's more chance for carbon dioxide to get into the cell
