| ribosome | proteins are built here by connecting amino acids together |
| centriole | are important for cell division |
| smooth endoplasmic reticulum | acts as a transportation network in a cell; does not have ribosomes attached |
| rough endoplasmic reticulum | acts as a transportation network in a cell; has ribosomes attached |
| nucleolus | sphere shape found inside the nucleus that helps make ribosomes for the ER |
| autotroph | organism that can make its own food |
