| What is in a eukaryotic cell? | membrane bound nucleus and organelles, single celled or multicellular |
| What is in a prokaryotic cell? | no nucleus, no membrane bound organelles, and single celled |
| Where can you find eukaryotic cells? | plants, animals, fungi, and protists |
| Where can you find prokaryotic cells? | eubacteria and archaea |

| What is an onion? | terrestrial photosynthetic plant and has a cell wall |
| Classification for pseudopodia. | Amoeba |
| Classification for cilia. | Paramecium |
| Classification for flagella. | Euglena |
| What is diffusion? | movement of molecules from an area of high concentration to an area of low concentration |
| What is osmosis? | movement of water molecules across a semi-permeable membrane from a high concentration of water to a low concentration of water |
| What is solvent? | the gas or liquid in which a substance is dissolved |
| What is solute? | substance that is dissolved in a gas or liquid |
| What is solution? | homogeneous mixture of two or more substances |
| What is tonicity? | measure of the concentration of solutes outside the cell relative to that inside the cell |
| What is hypertonic solution? | solution that contains a higher concentration of solute outside of the cell than inside the cell |
| What is isotonic solution? | solution that has the same concentration of solute as outside the cell |
| What is hypotonic solution? | solution that contains a lower concentration of solute inside the cell than outside the cell |
