Transport in plants — IGCSE Sciences - Co-Ordinated (0654) questions by topic
Comparing mass loss from a transpiring plant at 20 and 40 degrees Celsius, tracing water's pathway through soil, root and leaf, and naming labelled cells on a root cross-section photomicrograph make up the 6 transport-in-plants questions from 2023 and 2024, each worth 9 or 10 marks.
State, complete and explain are the top command words, with describe and match appearing where a diagram's parts must be paired with their function rather than simply named. Because photomicrograph questions reward exact identification of cell types, drill the labelling questions here and submit for instant marking, so any confused root or leaf structure is corrected before it repeats across a linked sub-question.
