Name the part that carries water and minerals from roots to the leaf.

• xylem

• phloem

• stoma

• guard cell

Name the part in a leaf that contains a lot of air spaces.

• Palisade cells

• Guard cell

• Spongy layer

• Lower epidermis

The role of the guard cell is to

• control the temperature of the plant

• control how much water enters the leaf

• control how much glucose is stored

• control the diffusion of gas and water vapour
