|---|
| nucleus | the control centre of the cell |
| nucleolus | small circular structure(s) within the nucleus; may be involved in protein synthesis |
| chromosomes | genetic material found in the nucleus |
| mitochondria | tiny, oval-shaped organelle that provides cells with energy |
| ribosomes | where proteins are made |
| endoplasmic reticulum | a series of "canals" that carry materials throughout the cell |
| golgi apparatus | a structure that stores proteins until needed for use inside or outside the cell |
| lysosome | saclike structure, formed by the Golgi apparatus, that contains proteins that can break down large molecules and other cell parts |
| chloroplast | organelle containing chlorophyll where photosynthesis occurs |
| cell membrane | semi-permeable; it controls what moves in and out of the cell |
| cell wall | non-living outermost covering that protects and supports plant cells |
| eukaryote | cell that has a membrane-bound nucleus |
| prokaryote | a cell with no nuclear membrane and few (if any) membrane bound organelles |
| vacuole | fluid-filled space containing water, sugar, minerals, and proteins |
| centriole | small protein structure critical to cell division, found only in animal cells |
