| Binary Fission | Prokaryotic cells divide by a process called .............. |
| cell wall | the ........... is made of protein sugars |
| shape | the cell wall gives the cell its ......... |

| active transport | some materials require ............... to pump them across the membrane |
| concentration gradient | active transport is required when materials are going against the ............... |
| partially permeable | some materials are let through and others aren't, therefore the membrane is........... |
