Leaf cell structure

• What does the waxy cuticle do?

  - It prevents water loss from the surface of the leaf
• What does the upper epidermis do?

  - It protects the leaf
• What does the palisade mesophyll do?

  - It takes in sunlight for photosynthesis
• What do the palisade cells contain lots of?

  - Chloroplasts for photosynthesis
• What does the spongey mesophyll do?

  - It allows gas exchange to occur
• What does the lower epidermis do?

  - It protects the lower surface of the leaf
• What do the guard cells do?

  - They control the opening and closing of the stomata
• What does the stomata do?

  - It controls water loss and gas exchange
• What do xylem cells do?


  - They transport water and mineral ions up from the stem to the leaf
• What do phloem cells do?


  - They transport dissolved sugars (and other nutrients) through the plant
