|---|---|
| structure in the cell that performs a specific function | organelle |
| area between the cell membrane & the nucleus | cytoplasm |
| supplies the cell with energy | mitochondria |
| mitochondria has ? membranes | 2 |
| the 2 membranes in the mitochondria are the _____ & ______ | outer & inner |
| the outer membrane is _____ & the inner is ________ | smoooth & folded |
| the name of the folds in the membranes are ____ | cristae |
| site of protein synthesis | ribosomes |
