How does carbon dioxide get into the leaves of a plant?

• It's absorbed by the roots
• It's made in a chemical reaction in the stem
• It enters through the stomata
• It goes through the flowers

How does most of the water needed by the plant get into its leaves?

• It enters through the stomata

• The roots absorb it and then it travels up the stem

• It's made during a chemical reaction in the leaf

• The flowers capture water and deliver it to the leaves

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
