| Cells | Animal and Plant |
| Cell organelles | All parts of the cells |
| Animal Cell | Nucleus, Cell membrane, Cytoplasm, Ribosome, Mitochondrion |
| Plant cell | Nucleus, Cell membrane, Cytoplasm, Ribosome, Mitochondrion, Cell Wall, Vacuole and Chloroplast |

| Cell membrane | Controls substances in and out of the cell |
| Cytoplasm | Watery fluid the cell organelles are in |
| Ribosomes | Proteins are made here |
| Mitochondrion | Powerhouse of the cell. Supplies energy to the cell, involved in respiration |
| Cell wall | Gives structure and support to the plant cell. Protects cell |
| Vacuole | Stores substances such as water and food |
| Chloroplasts | Contain a green pigment called chlorophyll that is used to make food for the plant through photosynthesis |
| Photosynthesis | Using sunlight to make food for plant |
