| A | B |
|---|
| lysosome | breaks down old cell parts - membrane bound |
| ribosomes | madeup of protein and RNA, assembles proteins |
| nucleus | control center - DNA hereditary material |
| nucleolus | makes ribosomes |
| golgi bodies | processes molecules for export |
| rough ER | site of protein synthesis has ribosomes |
| smooth ER | site of lipid synthesis |
| cell wall | only plants - gives plants shape made of cellulose |
| cell membrane | outer part of animal cell inner part of plant cells semi permeable |
| cytoskeleton | only animal gives cell System of tubules |
| Plant vacuole | one large one that holds water |
| animal vacuole | several small ones that hold food and water |
| cytoplasm | jelly like substance keeps organelles organized |
| chloroplast | only in plants holds chlorophyll green in color, where photosynthesis occures |
| prokaryotic cells | no nucleus mainly bacteria, some fungi and algae |
| Eukaryotic | has a nucleus, more complicated most other organisms |
| cell | basic unit of life, new cells must come from other cells |
| homeostasis | maintaining constant internal environment |
| Hook | first to name the structure cell |
| chromosomes | found in nucleus - made of DNA protein |
| flagella | animal only - used for movement |
| cilia | animal only - used for movement |
| mitochondria | site of cell respiration, powerhouse of cell membraned organelle |
| diffusion | molecules move from high concentration to low concentration |
| brownian motion | molecules are always in motion |
| concentration gradient | a uneven concentration must have for diffusion to occur |
