The leaf has a shiny, waxy cuticle around it to

• increase the rate of photosynthesis
• attract more light
• control water loss
• stop carbon dioxide and oxygen gases escaping

The role of the guard cell is to

• help control the temperature of the plant
• control how much water enters the leaf
• control how much glucose is stored
• control the movement of water vapour & gases
