1
If the light reactions stopped working, what would happen to the dark reactions?
They would not continue because it is one big reaction
They would continue, because they happen in the dark
They would continue, they don't depend on each other
They would not continue because it needs the ATP produced
2
Growing plants in a greenhouse can increase photosynthesis rate because it...
Enhances the amount of chlorophyll present
Keeps the plants sheltered
Increases the temperature
Keeps the plants in the shade
3

13
Why does a plant often have more than one light-trapping pigment present?
So that the plant can appear green
Because chlorophyll is in short supply
So that more visible light can be captured in photosynthesis
So that it can have multicoloured leaves in the autumn
