| Compartmentalisation | Dividing the cytoplasm into membrane-bound organelles. |
| Prokaryotes | Cells with a simple cell structure, without membrane bound organelles. |
| Eukaryotes | Cells that contain a nucleus and membrane bound organelles. |
| Light microscope | Microscope that uses a beam of light passing through one or more lenses to magnify an object. |
| Electron microscope | Microscope that forms an image by focusing beams of electrons onto a specimen. |
| Ultrastructure | The detailed structure of the internal components of cells as revealed by the electron microscope. |
