|---|---|
| OSMOSIS | The diffusion of water molecules across a selectively permeable membrane |
| CELL MEMBRANE | A cell structure that controls what enters and leaves the cell; is selectively permeable |
| CYTOPLASM | The gel-like substance in the cell that holds cell structures in place |
| EUKARYOTIC | A cell that contains a nucleus and other organelles |
| CELL | The basic unit of structure and function in all living things |
| PHOTOSYNTHESIS | The process by which producers capture and use the sun’s energy to make food for themselves |
| MITOCHONDRIA | A cell structure that produces most of the energy needed to carry out the cell’s functions |
| MEIOSIS | The process that produces four sex cells, each containing half of the usual number of chromosomes |
| RIBOSOME | A cell structure that makes proteins |
| CHLOROPLASTS | A cell structure found in plant cells that contains chlorophyll; where photosynthesis takes place |
| MITOSIS | The stage of the cell cycle during which the cell divides into two identical cells |
| ENDOPLASMIC RETICULUM | A cell structure that forms a passageway for proteins and other materials to be carried around the cell |

| CELL WALL | A cell structure found in plant cells that provides protection and support to the plant |
| PROKARYOTIC | A cell that does not contain a nucleus or other organelles |
| NUCLEUS | A cell structure that controls all of the cell’s activities |
| DIFFUSION | The process by which molecules move from an area of high concentration to an area of low concentration; does not use energy |
| TISSUE | A group of cells working together |
| ACTIVE TRANSPORT | The process by which molecules move from an area of low concentration to an area of high concentration; requires energy |
