Which of the following allow gases to enter and leave the leaf?

• cuticle

• chloroplast

• vein

• stoma

Answer explanation

Stoma (stomata if there is only one) are the openings that allow for gases to enter and leave the leaf. Guard cells are responsible for opening and closing the stoma.

Which layer contain the most chloroplasts?

• upper epidermis

• palisade mesophyll

• spongy mesophyll

• lower epidermis

Answer explanation

Use the diagram to find the symbol for a chloroplast and then search the diagram to see where there are the most of those 'chloroplasts'.

What structure is found between guard cells?

• cuticle

• stoma

• lower epidermis

• vein

Answer explanation

Guard cells are located on the outside of the stoma and control the opening and closing of the stoma.

Remembering the function of chloroplasts, in which part(s) of the leaf of the leaf is photosynthesis taking place? (choose all that apply)

• cuticle

• vein

• palisade mesophyll

• stoma

• air space

Answer explanation

The location of the chloroplast determines where photosynthesis will take place.
