Cell Organelles and Functions
🎯 WALT: We Are Learning To identify cell organelles and their functions
Success Criteria:
- I can name the main organelles in plant and animal cells
- I can match organelles to their correct functions
- I can explain why cells need different organelles
📚 Part 1: Organelle Functions
1. Which organelle controls what enters and leaves the cell?
Nucleus
Cell membrane
Mitochondria
Cytoplasm
2. Where does photosynthesis occur in plant cells?
Nucleus
Vacuole
Chloroplasts
Cell wall
3. Which organelles are found ONLY in plant cells? (Tick all that apply)
Cell wall
Chloroplasts
Large vacuole
Nucleus
Mitochondria
4. Complete this sentence: The _____________ is often called the "powerhouse of the cell" because it produces _____________.
5. What is the main function of the nucleus?
To make energy
To control the cell and contain DNA
To make food
To store water
🔍 Part 2: Matching Activity
6. Match each organelle to its correct function by drawing lines:
Organelle:
Cell membrane
Chloroplasts
Mitochondria
Vacuole
Cell wall
Function:
Provides support and protection
Stores water and maintains shape
Controls what enters and leaves
Makes energy (respiration)
Makes food (photosynthesis)
✏️ Part 3: Short Answer Questions
7. Explain why plant cells need a cell wall but animal cells do not.
8. A student looks at a cell under a microscope and sees chloroplasts. What type of cell is it and how do you know?
9. Extension Question: Muscle cells contain many more mitochondria than skin cells. Suggest why this is the case and explain your reasoning.
10. Challenge: Design a specialised cell for a specific job. Name your cell, describe its function, and explain which organelles it would need lots of and why.
Differentiation Support: If you need help, focus on questions 1-6 first. Use your textbook pages 45-48 for reference.
