Explain why the student left the plant for five minutes before starting recording. She used the valve to allow water from the reservoir to move the air bubble back to the start of the graduated scale. She then recorded the position of the bubble every minute for five minutes. She then set up an electric fan to blow air...

What examiners said
Candidates were asked to outline the movement of water through a leaf during the process of transpiration. Some missed the instruction to focus on the leaf and instead described the whole transpiration stream. In these cases they were generally able to pick up marks when their answers started to describe the journey of water molecules through the leaf. Many candidates were able to give accurate a...
— Examiner report, October/November 2022, 5090/22 Q8(b) (Cambridge)
Many candidates gained full credit for reference to water vapour evaporating through the stomata, or for correct reference to ‘diffusion’ and ‘air spaces’. There was an encouraging number of responses that correctly included all six marking points.
— Examiner report, May/June 2022, 5090/22 Q5(b) (Cambridge)
Candidates were asked to compare the transport of water in humans and flowering plants. It was pleasing to see that some candidates did attempt to compare the similarities and differences and these candidates generally scored well here. Far too often, however, candidates were not comparing the transport systems so did not gain some of the available marks. For example, a candidate would explain tha...
