In the diagram, label C is pointing to the palisade cells. Palisade cells . . .

Select two options.

• have air spaces between them that allow gases to diffuse through the leaf.

• are situated at the top of the leaf so that they can absorb as much light as possible.

• contain a large number of chloroplasts, which carry out the photosynthesis reaction.

• are a layer of transparent cells that light can pass through.
