| nutrients | substances which are needed for a living thing to live and grow |
| tissue | similar cells working together |
| organ | different types of tissue working together |
| organ system | groups of organs working together |
| cell membrane | thin layer surrounding all cells which allows water and dissolved materials to pass in and out of the cell |
