๐ฏ Common Question Types:
- Compare questions: Know similarities AND differences between plant and animal cells โ always mention both sides
- Function questions: Match each organelle to its specific function โ use precise language like "site of aerobic respiration" not just "makes energy"
- Explain adaptation: Link the structure of specialised cells to how they carry out their function
๐ Key Command Words:
- "State" โ give the name or fact, no explanation needed
- "Describe" โ say what it looks like or what it does, with detail
- "Explain" โ give a reason using "because" โ this is where marks are won or lost
- "Compare" โ you MUST mention both things being compared in every point
โ ๏ธ Common Mistakes to Avoid:
- Writing "the cell wall controls what enters" โ it's the cell MEMBRANE that's selectively permeable
- Forgetting plant cells have mitochondria โ they respire too, not just photosynthesise
- Mixing up ribosomes and mitochondria โ ribosomes make proteins, mitochondria release energy
This exam tips covers Exam Tips for Cell Organelles within Cell Organelles for GCSE Biology. Revise Cell Organelles in Cell Biology for GCSE Biology with 12 exam-style questions and 15 flashcards. This is a high-frequency topic, so it is worth revising until the explanation feels precise and repeatable. It is section 13 of 14 in this topic. Treat this as a marking guide for what examiners are looking for, not just a fact list.
Practice questions for Cell Organelles
Scientists studying mitochondria use electron microscopes rather than light microscopes. Which statement correctly explains why electron microscopes are more useful for studying cell ultrastructure?
The diameter of a ribosome is approximately 0.00002 mm. (a) Write this diameter in standard form, in millimetres. (b) Convert this diameter into nanometres (nm).
