| A | B |
| nucleus | the control centre of the cell |
| nucleolus | small circular structure(s) within the nucleus; may be involved in protein synthesis |
| mitochondria | where energy in the form of ATP is produced |
| ribosomes | where proteins are made |
| endoplasmic reticulum | transport system in the cell |
| golgi apparatus | packages up protein |
| lysosome | special type of vacuole that breaks down large molecules and cell parts |
| chloroplast | where photosynthesis occurs |
| cell membrane | semi-permeable; it controls what moves in and out of the cell |
| cell wall | 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 | stores wastes, water, food |
| cilia | short hair-like structures used for movement |
| flagella | whip-like structure used for movement |
| pseudopodia | "false foot" used for movement |
| Features of Plant Cells | Cell wall, Chloroplasts, Large Vacuoles |
| Cell Theory | 1. Cells are the basic unit of life 2. All organisms are composed of one or more cells. 3. Cells come from existing cells |
| Features of Animal Cells | No cell wall, lysosomes |
