| A | B |
| Cell wall | made of cellulose, strengthens the cell, found only in plants |
| Cell membrane | surround the cell and controls what comes in and out of it |
| Vacuole | "storage tank" of the cell - usually contains fluid - they are larger in plants than in animals |
| Chloroplasts | contain chlorophyll - this is needed for photosynthesis in plants |
| Nucleus | controls what the cell does and stores genetic information |
| Cytoplasm | gel-like substance inside cell - organelles "float" it in - molecules move through it in the cell |
| Ribosomes | attach to the endoplasmic reticulum (ER) to make or synthesize proteins |
| Mitochondria | produce energy (ATP) for the cell - the "powerhouse" of cells |
| lysosomes | break down or "digest" molecules in the cell |
| golgi apparatus | helps transport proteins made by ribosomes out of the cell |
| centrioles | help in organizing chromosomes during cell division |
| nucleolus | programs the formation of ribosomes in the nucleus |
| endoplasmic reticulum (ER) | carries proteins and other substances through the cytoplasm |
| nucleoid | a region of cytoplasm where DNA is located in a certain type of cell - it has no membrane |
| flagellum/flagella | hairlike structures found on certain types of cells that help those cells move |
| prokaryote | uni-celled organism with no membrane-bound organelles or defined nucleus |
| eukaryote | multi-celled organisms with membrane-enclosed organelles and a well-defined nucleus |
