internal structure of leaf

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

Most of the chloroplast cells are found in the

• upper epidermis
• pallisade mesophyll layer
• lower epidermis
• stomata

The important gases, carbon dioxide and oxygen, enter and leave the leaf through the

• upper epidermis
• phloem
• stomata
• guard cells

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
