- What Makes Something Alive — The eight processes every living organism carries out — and why a fire, which seems to do several of them, is not alive.
- The Four Eukaryote Groups — Plants, animals, fungi and protoctists — how to tell them apart from their features, and the named examples the specification expects.

Specification coverage
Topic 1 The nature and variety of living organisms (a) Characteristics of living organisms — statements 1.1–1.2
Assessment objectives: AO1, AO2. Suggested learning time: 30 minutes.
Required knowledge
- The characteristics of living organisms: nutrition, respiration, excretion, growth, movement, control (sensitivity), reproduction
- That these processes distinguish living organisms from non-living material
Required skills
- Apply the characteristics to decide whether something is a living organism
- Use the correct term for each process
How it is examined
- Multiple-choice and short-answer recall
- Application of the content to an unfamiliar context
- Extended open-response, marked on the quality of a connected explanation
Common mistakes
- Confusing respiration with breathing. Respiration is a chemical reaction in every cell; breathing is ventilation.
- Confusing excretion with egestion. Excretion removes the waste products of metabolism; egestion removes undigested food.
