What is the function of the waxy cuticle on leaves?

• To stop rain entering the leaf

• To prevent excess loss of water from the leaf

• To reflect sunlight

• To allow gas exchange

How is the spongy mesophyll adapted for gas exchange?

• It is close to the palisade cells

• It contains chloroplasts

• It has air spaces and a large surface area

• It contains lots of small cells

Why are palisade cells arranged at the top of the leaf?

• So that they are far away from the stomata

• So that sugars made on photosynthesis can be transported to the phloem

• So that chloroplasts are concentrated in one place

• So that chloroplasts receive the maximum amount of sunlight
