Use the phrases and diagrams below to make a poster showing the important factsabout plants and photosynthesis. Add your own labels and drawings if you need to.Your poster should include information on:

• which substances plants use to produce biomass• what source of energy is needed for photosynthesis• what happens in leaves, and how they are adapted to their function• what happens in roots, and how they are adapted to their function.

Roots take in water andmineral salts from the soil.

Water and mineral salts pass up through the stem of the plant

in xylem tubes.Light is needed for photosynthesis.

Leaves have a large surface area. Palisade cells have a lot of chloroplasts.

carbon dioxide + water (+ light energy) → glucose + oxygen

Root hair cells have alarge surface area to help

them absorb water.

Carbon dioxide diffusesinto leaves through the

stomata.
