The table shows information about two types of microscope.
Table
| Microscope | Maximum useful magnification | Resolution in nm\text{nm}nm | Specimens that can be viewed |
|---|---|---|---|
| Light | ×1500\times 1500×1500 | 200 | living or dead |
| Transmission electron | ×2 000 000\times 2\,000\,000×2000000 | 0.2 | dead only |
A student wants to watch chloroplasts moving around inside living Elodea leaf cells.
Which microscope should the student use, and why?
the electron microscope, because its resolution is higher
the electron microscope, because its magnification is higher
the light microscope, because the cells can be kept alive
the light microscope, because its resolution is higher
130 exam-style questions on OCR GCSE Biology 1.1 Cell structures, covering 1.1.1 Viewing cells with light microscopes, 1.1.2 Sub-cellular structures and functions, and 1.1.3 Electron microscopy and resolution. Each one has a worked solution and a mark scheme showing where the marks go.
