| cell | the basic unit that makes up living things |
| organelles | small structures contained in plants and animals which perform specific functions in the cell |
| nucleus | this organelle is the "brain" of the cell because it directs the activities of the cell |
| cytoplasm | the jellylike material between the cell membrane and nucleus |
| cellular respiration | a process involving a series of chemical reactions that break down glucose (sugar) to make energy |
| vacuole | storage tank for the cell-may contain water, food, waste, etc. |
| diffusion | a process that spreads substances through a gas or liquid |
| lysosome | animal cell organelle that digests food, proteins, waste, old cells, etc. |
| endoplasmic reticulum | highways of the cells, transport proteins |
| mitochondria | powers the cell-releases energy |
| chloroplast | plastid that contains chlorophyll |
| osmosis | a special form of diffusion that lets water pass, but keeps out many things that are dissolved in the water |
| ribosome | is responsible for making protein and is contained in "rough" endoplasmic reticulum |
| Golgi apparatus | receives proteins and processes and packages them for shipment outside the cell |
| tissue | a large group of similar specialized cells |
| organ | a group of related tissues that perform a specific function |
| organ system | a group of related organs that work together to perform a specific function |
| glucose | a type of "sugar" that is the building block for other kinds of sugars |
