| In a salt water solution, the salt is known as the ___. | solute |
| If glucose can enter a cell through the cell membrane, the ___ is said to be permeable. | cell membrane,
|

| A solution that has the same concentration of solutes as the interior of a cell is known to be ____. | isotonic |
| The type of protein that a hormone could attach to on the outside of a cell membrane is called a ____ protein. | receptor |
| The type of cell membrane protein that allows your body to recognize your own cells is called a ____ protein . | marker |
The process pictured below is called ____.,  | exocytosis,
|
The plant cells pictured below have been soaking in a ____ solution.,  | hypertonic |

The process pictured below is called ____.,  | endocytosis,
|
| When large molecules need the help of protein channels to cross the cell membrane, the process that is occurring is called ______. | facilitated diffusion |
| The type of cell membrane protein that moves molecules from areas of low concentration to areas of high concentration is called a ___. | pump |
