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

• stomata
• guard cells
• xylem cells

Transpiration helps the plant

• make more sugars at night
• move water from the roots to the stem and leaves
• move sugars from the leaf to be stored in the stem & roots
• make more chloroplasts
