1
Where does photosynthesis take place in a plant cell?
Answer & explanation
Correct: option C
Chloroplasts contain chlorophyll and are the site of photosynthesis. Mitochondria are where aerobic respiration happens.
2
Which is the correct balanced symbol equation for photosynthesis?
Answer & explanation
Correct: option B
Option d is the equation for respiration, the reverse. Option b is the correctly balanced photosynthesis equation.
3
Photosynthesis is described as endothermic because:
Answer & explanation
Correct: option B
Endothermic reactions take in energy. Photosynthesis takes in light energy and stores it in glucose bonds.
4
Which of the following is NOT a reactant in photosynthesis?
Answer & explanation
Correct: option C
Oxygen is a PRODUCT of photosynthesis, not a reactant. Light energy is required but is a condition, not a chemical reactant.
5
What is the role of chlorophyll?
Answer & explanation
Correct: option B
Chlorophyll is the green pigment that absorbs light energy needed for the photosynthesis reaction.
