Analogy
Animal cell structure
Use the shape first, then attach the job of each part.
- Nucleus
- Controls cell activities and contains genetic material.
- Cytoplasm
- Jelly-like site of many chemical reactions.
- Cell membrane
- Controls what enters and leaves the cell.
- Mitochondria
- Release energy for cell processes.
Cell structure is like a living system solving a small survival problem: each part has a job, and the answer depends on how those jobs connect.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Why it matters
Real-world use
Cell structure helps explain health, ecosystems, medicine and how organisms stay alive. Example: A root hair cell has a long extension to increase surface area for absorbing mineral ions.
Why now: Real examples make the mark-scheme words easier to remember.
Do this: Connect one key word to the example.
