Student lesson
- Animal cells have no cell wall or chloroplasts.
- Mitochondria release energy.
- The membrane controls entry and exit.
- Specialised cells suit their jobs.
Words to know
parts that release energy from food
the thin layer that controls what enters and leaves
a cell adapted for a particular job
a cell that carries oxygen
1. Discover: The sprinter
Kwesi sprints 100 metres. His muscle cells need energy fast. “Your muscle cells have lots of mitochondria,” says his coach. “They release energy from food and oxygen.”
Think: Why do muscle cells need so many mitochondria?
2. Understand: Animal cells
Idea 1: Parts
An animal cell has a cell membrane, cytoplasm, a nucleus and mitochondria. It has no cell wall and no chloroplasts.
Idea 2: Compare
Plant cells have a wall, large vacuole and chloroplasts; animal cells are usually rounder or irregular and store energy as fat or glycogen.
Idea 3: Specialised
A specialised cell suits its job: nerve cells are long to carry signals, red blood cells are flexible discs that carry oxygen, muscle cells contract.
3. Worked examples
Example 1 (I show you): Label
Parts.
- Membrane.
- Nucleus.
- Mitochondria.
Answer: Labelled sketch.
Example 2 (We do it together): Compare
Plant and animal.
- Wall.
- Chloroplast.
- Shape.
Answer: Differences.
Example 3 (You try): Match
Specialised.
Show the steps and answer
- Nerve.
- Red blood.
- Muscle.
Answer: Structure fits job.
Did you know?
Red blood cells have no nucleus, which leaves more room to carry oxygen.
Why this matters
Cell structure explains how our bodies work.
4. Explore: Cell modelling
Build a model of an animal cell using safe clay, beads and a plastic bag and label each part, comparing it with a plant cell model.
- Choose materials.
- Build the cell.
- Label parts.
- Compare with plant.
Think about it: what did you notice?
What did you notice? The animal cell had no wall.

If a learner struggles
- Find the misconception: “Animal cells have walls.” No.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Label and compare animal cells.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child studies animal cells. You do not need to be an expert to help.
- Model with clay.
- Ask “What does this part do?”
- Wash hands.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: name animal cell parts; compare with plant cells; describe specialised cells; relate structure to function.
Prerequisite knowledge. Grade 5 ideas: living things, plant and animal parts and using a hand lens.
Materials. Modelling clay, beads, bags. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.
Preparation. Prepare materials.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Show a running photo and ask, “Which cells need most energy?”
Explanation (10 min). Teach animal cells.
Guided activity (10 min). Learners build.
Independent activity (10 min). Learners compare.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Which part? Why that shape?
Teacher explanation notes. Start with real objects and safe, hands-on observation. Then talk about what was seen, then draw and write. Always say “how do you know?”. Keep to the safety notes, and use local, safe materials.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and pictures, short sentences and a partner. Let learners point, show or draw instead of writing. Extension. Ask learners to find a new example at home and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “Animal cells have walls.” No.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 10-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Label and compare animal cells. Enrichment. Look for one new example near your home or school, draw it and explain it to someone. Homework. See above.
Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
