What examiners said
It was important for candidates to read the stimulus material carefully to identify that this investigation was conducted with light from every direction, and so the direction of light was not a factor in the investigation. Candidates that recognised the effect was due to gravity generally answered this question well.
— Examiner report, May/June 2025, 0970/41 Q6(a)(i) (Cambridge)
Many candidates knew that nitrate ions were transported into the root hair cell by active transport, with only a few suggesting diffusion or osmosis. Candidates often correctly referred to the difference in concentration outside and inside the cell although a small number of candidates then went on to contradict themselves by stating the ion moved down a concentration gradient. A few candidates al...
— Examiner report, May/June 2025, 0970/42 Q5(a)(i) (Cambridge)
Many candidates correctly stated root hair cell but some missed out the hair and just stated root cell which is insufficient. Describing the adaptation proved difficult and most candidates stated the function of the cell, not how it is adapted.
