12
During photosynthesis, sunlight energy can be captured in pigments called:
all of the above
carotenoids
chlorophylls
xanthophylls
13
Why does a plant often have more than one light-trapping pigment present?
So that it can have multicoloured leaves in the autumn
So that more visible light can be captured in photosynthesis
So that the plant can appear green
Because chlorophyll is in short supply
