| organelles | cell component that performs a specific function |
| cells | the basic units of structure and function of living things |
| cell membrane | a bilipid layer with embedded proteins determining what goes in and out |
| nucleus | large organelle that controls the cell's function |
| eukaryotes | complex cells with a nucleus and membrane bound organelles |
| prokaryotes | primitive cells without a nucleus such as bacteria |
| cytoplasm | all the material between the nucleus and the cell membrane |
| mitochondria | site of ATP (energy) production by cellular respiration |
| ribosomes | organelles in charge of protein synthesis |
| endoplasmic reticulum | a cells system of membranous tubules and sacs |
| rough endoplasmic reticulum | contains ribosomes so it manufactures and ships proteins |
| smooth endoplasmic reticulum | makes lipids & steroids and transports them |
| Golgi apparatus | modifies, processes, and packages proteins for export |
| lysosomes | spherical organelles that contain digestive enzymes |
| cytoskeleton | gives the cell shape and ability to move |
| microfilaments | the "muscles" of the cell made of actin protein |
| microtubules | stiff proteins that give the cell shape |
| flagella | a long whiplike projection from a cell's surface that help it move |
| nuclear membrane | the double membrane surrounding the nucleus |
| nucleolus | organelle in the nucleus that makes ribosomes |
| cell wall | rigid cellulose structure that surrounds plant cells |
| vacuoles | fluid-filled organelles in plants that store water, enzymes, and wastes |
| chloroplast | green plastids in plants that photosynthesize |
