| eukaryotic cell | cell with a membrane bound nucleus |
| prokaryotic cell | cell without a membrane bound nucleus |
| nucleus | largest organelle in the cytoplasm of a eukaryotic cell that contains long strands of DNA |
| chromatin | long strand of proteins and DNA (hereditary material) |
| cytoplasm | gel-like material inside the cell and outside the nucleus |
| endoplasmic reticulum (ER) | folded membrane extending from the nucleus to the cell membrane that moves materials around in the cell |
| ribosomes | small structures that recieve directions from the hereditary material in the nucleus on how to make specific proteins |
| Golgi bodies | membrane-covered sacs that package and move proteins to the outside of the cell |
| mitochondria | where food molecules are broken down and energy is released |
| Lysosomes | contain chemicals that digest waste and worn-out cell parts |
| vacuoles | fluid filled temoprary storage areas |
| cell wall | rigid structure outside the cell membrane that supports and protects plant cells |
| chloroplasts | organelles in plant cells in which light energy is changed into chemical energy in the form of a sugar |
| tissue | groups of similar cells that do the same sort of work |
| organ | structure made up of different tissues that work together to do a particular job |
