- Investigating Cells
- The Size of Cells
- Centimetre - 1 x 10^2
- Millimetre - 1 x 10^3
- Micrometre - 1 x 10^6
- Nanometre - 1 x 10^9
- Using Microscopes to Look at Cells
- Resolution - the ability to distinguish between two objects / how clear the image is
- Electron microscope
- Passes electrons through the specimen rather than light
- Gives much better resolution
- Cells can be seen in much finer detail e.g.
- The structures inside mitochondria can chloroplasts can be studied
- Ribosomes can be seen and their role in making proteins can be studied
- Magnification is how many times larger the image is than the real object
- Magnification = size of object / size of real object
