| Requires no energy to move materials from a high concentration to a low concentration | Passive Transport |
| When the concentration of substances is the same inside and outside of the cell | Equilibrium |
| The diffusion of water through a membrane. | Osmosis |
| The movement from a high to low concentration with the help of a transport protein | Facilitated Diffusion |
| If the red blood cell is 80% water and 20% salt, and it is put into 100% water, what type of solution is it in and what will happen to the cell? | Hypotonic, it will swell |
| If the red blood cell is 80% water and 20% salt, and it is put into 80% water and 20% salt, what type of solution is it in and what will happen to the cell? | Istotonic, the shape will not change |
| If the red blood cell is 80% water and 20% salt, and it is put into 50% water and 50% salt, what type of solution is it in and what will happen to the cell? | Hypertonic, it will shrink |
| The movement of materials from a low concentration to a high concentration, energy is required | Active Transport |
| The movement of materials from a high to low concentration (no membrane is needed) | Diffusion |
| When the concentration of water is higher outside the cell than in | Hypotonic solution |
| When the concentration of water is lower outside the cell than inside. | Hypertonic solution |
| When the concentration of water is the same inside and outside of the cell | Isotonic solution |
| The movment of materials into a cell by way of a vesicle (small bubble) | Endocytosis |
| The movement of materials out of the cell by way of a vesicle (small bubble) | Exocytosis |
| Organisms that are made of more than one cell | Multicellular |
| When a cell has special features that makes it good at one particular job | Specialized |
| The level of organization above the cell, it is made of a combination of cell types | Tissue |
| The level of organization above tissues, example: heart | Organ |
| The level of organization above organs | Organ System |
