# Summary of Sections 1 and 2

- The internal structure of cells is studied by transmission electron microscopy, which allows cell organelles to be visualised.
- Immunoelectron microscopy allows the localisation of molecules to specific parts of cells.
- Cell fractionation techniques, including ultracentrifugation, allow cell organelles to be separated for subsequent biochemical analysis.
