Analogy
Transport in cells
Check the direction and the particle first. That tells you whether it is diffusion, osmosis or active transport.
- Diffusion
- Particles move high to low concentration. No energy.
- Osmosis
- Water moves through a partially permeable membrane.
- Active transport
- Substances move low to high concentration using energy.
- Exam move
- Name the process, then describe direction and membrane or energy.
Transport in cells 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
Transport in cells helps explain health, ecosystems, medicine and how organisms stay alive. Example: Root hair cells use active transport to absorb mineral ions from dilute soil water.
Why now: Real examples make the mark-scheme words easier to remember.
Do this: Connect one key word to the example.
