| 911116779 | cytosol | the semifluid part of the cytoplasm within which various particles and organelles are suspended | |
| 911116780 | cytoplasm | the entire region between the nucleus and the plasma membrane | |
| 911116781 | plasma membrane | selective barrier that allows passage of oxygen, nutrients, and waste | |
| 911116782 | nucleus | contains most of the genes and is typically the largest organelle | |
| 911116783 | nuclear envelope | encloses nucleus, is a double membrane, covered in pores | |
| 911116784 | nuclear lamina | netlike array of protein filaments that maintain the shape of the nucleus | |
| 911116785 | chromosomes | structures containing genetic information within the nucleus. | |
| 911116786 | chromatin | complex of proteins and DNA that makes up a chromosome | |
| 911116787 | nucleolus | where rRNA is synthesized from DNA instructions, | |
| 911116788 | Ribosomes | made of rRNA and protein, carry out protein synthesis, 2 kinds, free and bound ribosomes. | |
| 911116789 | Free Ribosomes | suspended in cytosol, enzymes that catalyze first steps of sugar breakdown | |
| 911116790 | Bound Ribosomes | bound to the endoplasmic reticulum, make protein bound for insertion into membranes, packaging within lysosomes, or for exporting the cell |
