What is the purpose of photosynthesis?
To release energy
To create glucose
To grow
To get oxygen for respiration
Which of these is the correct equation for photosynthesis?
6O2 + C6H12O6 --> 6CO2 + 6H2O
6O2 + 6CO2 --> C6H12O6 + 6H2O

A student wanted to see if covering a leaf in foil would stop it from producing starch. Why should the student put the plant in a dark cupboard for 48 hours before returning it to the light and starting the experiment?
To make the results reliable
So that the plant would photosynthesise faster when returned to the light
So that any starch already in the leaf was used up by the plant
