What role do roots play in photosynthesis?
They supply water to the leaves They capture sunlight They make chlorophyll They produce oxygen
Which tree keeps its needles in winter and can therefore photosynthesise all year?

In the leaves In the roots In the stem In flowers
Which plants can NOT photosynthesise?
Mushrooms Grass blades Pine trees Ferns

Their flat, wide shape Their thick structure Their smell Their soft texture
What happens to photosynthesis in winter?
It slows down due to less sunlight It goes faster because of the cold It stops altogether It remains exactly the same

To maximise the light surface and facilitate gas exchange To better retain water To better resist wind To repel insects
Which substance serves as an electron donor in photosystem II?
Water NADPH Glucose CO2
What is the difference between photosynthesis and chemosynthesis?
Photosynthesis uses light energy, chemosynthesis uses chemical energy Photosynthesis produces CO2, chemosynthesis produces O2 Photosynthesis takes place in animals, chemosynthesis in plants There is no difference between the two processes
Why do underwater plants often have different photosynthetic adaptations?
Because light under water is otherwise filtered and attenuated Because they can't use CO2 Because they do not produce oxygen Because they photosynthesise only at night
