Explain how cell links to this AQA GCSE Biology objective: apply understanding of cell differentiation to explain and interpret GCSE Biology exam questions.

A strong answer should state the relevant biological idea, explain how it works in Cell differentiation, and link it directly to Cell structure.

This exam-style response should address "Apply understanding of cell differentiation to explain and interpret GCSE Biology exam questions." 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 9c3dc4 to keep the explanation distinct. Variant 112 checks written explanation rather than multiple-choice recognition.
