Organisation of the organism (cells) — IGCSE Science - Combined (0653) questions by topic
Identifying organelles and their functions from animal and plant cell diagrams runs through this topic: naming the structure that lets molecules in and out of a cell, spotting which organelle is absent from animal cells, and correcting a mislabelled plant-cell diagram. Identify, state and name lead the command words, and identify wants a specific organelle picked out rather than a general cell feature.
This set has 12 real questions from 2024 to 2025 papers, worth 1 to 10 marks, so diagram-based labelling sits beside short functional explanations. Practising with instant marking is well suited here, since a swapped label, such as vacuole for nucleus on a plant-cell diagram, is caught immediately rather than repeated across further questions.
