|---|---|
| three domains of life |  bacteria, archaea, eukarya |
| eukarya | eukaryotes can be single or multi-celled plants, animals, fungi and protists |
| nucleolus | The organelle where ribosomes are made, synthesized and partially assembled, located in the nucleus |
| nuclear envelope | layer of two membranes that surrounds the nucleus of a cell |
| ribosomes | site of protein synthesis |
| functions of nucleus | protects DNA controls passage of material in and out of nucleus |
| endomembrane system | endoplasmic reticulum (ER), golgi apparatus, various vesicles |
| rough ER | studded with ribosomes and synthesizes proteins |
| smooth ER | that portion of the endoplasmic reticulum that is free of ribosomes |
| golgi apparatus | stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum |
| transport vesicles | A tiny membranous sac in a cell's cytoplasm carrying molecules produced by the cell. |
| lysosomes | An organelle containing digestive enzymes |
| peroxisomes | detoxification |
| vacuoles | debris collection |
| central vacuole | A membranous sac in a mature plant cell with diverse roles in reproduction, growth, and development. |
| chloroplasts | convert light energy into chemical energy |
| mitochondria | convert chemical energy into ATP |
| endosymiosis theory | one species lives inside another |
| cytoskeleton | a microscopic network of actin filaments and microtubules in the cytoplasm of many living cells that gives the cell shape and coherence |
| microfilaments | fine, threadlike proteins found in the cell's cytoskeleton |
| microtubules | are hollow tubes, like plumbing pipes that maintain the shape of the cell and serve as tracks for organelles to move along within the cell |
