🧬 AQA Biology Paper 1 – Cell Biology (Higher)

1️⃣ Cell Structure

Animal vs Plant Cells

Animal Plant
Structure
Cell Cell

Nucleus ✅ ✅

Cytoplasm ✅ ✅

Cell
✅ ✅
Membrane

Mitochondria ✅ ✅

Ribosomes ✅ ✅

Cell Wall ❌ ✅

Chloroplasts ❌ ✅

Vacuole ❌ small ✅ large

Tip: Plant cells have cell wall, chloroplasts, large vacuole. Animal cells
don’t.



2️⃣ Functions of Organelles

 Nucleus – controls cell, contains DNA

 Cytoplasm – site of chemical reactions

 Cell membrane – controls what enters/exits

 Mitochondria – aerobic respiration, energy production

 Ribosomes – protein synthesis

 Chloroplasts – photosynthesis

 Cell Wall – supports plant cells

 Vacuole – stores water, maintains turgor
