| Organelles | Structures inside the cell that maintain the life of the cell. |
| Golgi apparatus | Responsible for transporting proteins and other materials. |
| Ribosomes | Organelle where amino acids are linked together. |
| Endo Plasmic Reticulum | System of folds and channels that are responsible for transporting materials through the cell. |
| Lysosomes | Small sac-like organelles that contain enzymes. |
| Diffusion | Movement of particles from high to low concentration. |
| Osmosis | Water passing through the cell membrane. |
| Semi-permeable | Some materials can pass through it, while others cannot. |
| Passive transport | No energy needed to move materials into orr out of the cell. |
| ATP | Provides the energy needed for active transport. |
| Active transport | Molecules move against the concentration gradient low to high. |
