Light and Electron Microscopes
We previously learnt about cell
specialisation by covering the
process and timing of cell • Cells can be seen with microscopes. Microscopes magnify small
differentiation. We concluded by
learning the importance of cell things that can’t usually be seen by the naked eye. This allows us to
differentiation in making a cell view cells within organisms
specialised.
• Light microscopes were created first. Light microscopes have a
magnification power of up to x2000. They use the beams of light and
lenses in order to magnify a living object to create an image. They are
cheap and portable and can be used to see cells and large organelles,
