What examiners said
Many candidates recognised that the vacuole would appear smaller. Fewer were able to draw the detachment of the cell membrane from the cell wall.
— Examiner report, May/June 2025, 0973/42 Q1(d) (Cambridge)
Most candidates gained at least partial credit. It was usually the medium or high sugar concentration that they correctly identified.
— Examiner report, October/November 2020, 0973/31 Q7(a)(i) (Cambridge)
The descriptions of the immersed cells were often chosen correctly.
