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

If guard cells are swollen with water, then they are more likely to be ...

• OPEN with stomata

Which carries water and minerals from roots to other parts of the plant?

• xylem

• phloem

• stoma

• guard cell

When water evaporates out of the leaf's stomata it is called

• photosynthesis

• transpiration

• transport

• xylem

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
