What examiners said
Most candidates correctly recognised process X as respiration. The most common incorrect responses were transpiration and diffusion. Most correctly stated sunlight, but some used insufficient terms such as sun and solar. Almost all stated that the rate increased. The majority identified the correct time from the graph.
— Examiner report, May/June 2025, 0654/41 Q1(b) (Cambridge)
Some candidates were able to write down the word equation for photosynthesis. Sunlight was often suggested as a reactant.
— Examiner report, February/March 2025, 0654/32 Q1(b)(ii) (Cambridge)
Light energy was correctly identified as the energy used in photosynthesis. Chemical energy and heat energy were common errors.
