Describe one way a GCSE Biology question could test cell in Cell differentiation.

The question could ask for a definition, explanation, comparison, practical interpretation, or application depending on the wording of the objective.

This exam-style response should address "Describe the key ideas and required knowledge in cell differentiation for AQA GCSE Biology 8461." by naming the key biological idea, explaining how it works in Cell differentiation, and linking it back to Cell structure. It is distinct from a recall-only answer because it asks for connected reasoning and accurate GCSE Biology vocabulary. This version focuses on Cell differentiation within Cell structure and uses the question reference bee91a to keep the explanation distinct. Variant 106 checks written explanation rather than multiple-choice recognition.
