Question: The main function of the leaves of a plant are:
A: to provide shade for the roots
B: to provide oxygen for us to breathe
C: to provide food for the plant
D: to clear carbon dioxide out of the air
Answer: C
I would want to find out if they have understood that leaves provide food for the plants and that oxygen is a by-product.
If there were children who choose A, B, or D I would ask them to explain the answer and then ask other children to defend their answer – then go back to the question – it asked what the main or primary function of leaves was.
