Animal versus Plant Cells
Organelles are compartmentalised structures that serve specific purposes
Animal Cells
Plant Cells
Examples of eukaryotic organelles include:
• 80S ribosomes – Responsible for protein synthesis (translation)
• Nucleus – Stores genetic information (site of transcription)
• Mitochondria – Site of aerobic respiration (ATP production)
• Endoplasmic reticulum – Transports materials between organelles
• Golgi complex – Sorts, stores, modifies & exports secretory products
• Centrosomes – Involved in cell division (mitosis and meiosis)
︎No chloroplast
Have chloroplast
No cell wall
Cell wall (cellulose)
No plasmodesmata
Plasmodesmata
Temporary vacuoles
Large central vacuole
Cholesterol present
in the cell membrane
No cholesterol in
the cell membrane
Glucose → glycogen
Glucose → starch
Organelles found only in specific cell types include:
• Chloroplasts – Site of photosynthesis (plant cells only)
• Lysosomes – Breakdown of macromolecules (animal cells)
