| A | B |
| Nucleus | Regulates all cell activities |
| Cell Membrane | Is made out of phospholipids and proteins |
| Mitochondrion | Site of cellular respiration "power house" |
| Lysosome | Suicide Sacks that contain digestive enzymes |
| Rough Endoplasmic Reticulum | Contains Ribosomes, transports proteins and other materials |
| Smooth Endoplasmic Reticulum | Contains no ribosomes, stores proteins |
| Gogi complex (apparatus) | Processes and packages proteins |
| Nucleuolus | Dark spot of chromatin in the nucleous where ribosomes are produced |
| Cytoplasm | Colloid that contains water and nutrients and supports the organelles |
| Organelles | The parts of a cell with a particular function |
| Prokaryotic | Cells with no true nucleus and no membrane bound organelles |
| Eukaryotic | Cells that contain a true nucleus and membrane bound organelles |
| Centrioles | Only in animal cells, aid in cell division |
| Ribosomes | Produce Proteins |
| Chloroplast | Found only in plants, site of photosynthesis |
| Vacuoles | Large storage sacks found mainly in plants |
| Cell Wall | Structure in plants made of cellulose that is outside of the cell membrane |
| Chromatin | Thin strands of DNA and proteins found in the nucleus of a cell. |
| Cell | Smallest unit of life |
| Cytoskeleton | Long protein filaments in the cytosol that support the cell. |
