Transport in plants — IGCSE Sciences - Co-Ordinated (0973) questions by topic
Transport in plants questions cover translocation of substances between source and sink, investigating transpiration rate at two temperatures by mass loss, identifying stem tissue at a labelled position, and locating xylem in a dicotyledonous root cross-section, worth from 1 to 9 marks in this IGCSE Co-ordinated Sciences set.
Identify, state and complete are the only top command words here: identify a labelled tissue by its position relative to the stem's outer edge, not by guesswork. 11 real questions from 2023 to 2025 papers sit here. Submitting each answer for instant marking checks whether xylem or phloem is correctly placed on a cross-section diagram.
