Asses the impact of the development of the electron microscope on our understanding of the cell and it’s role in cell theory. Since the invention of the electron microscope in 1928 scientists have been able to study the ultrastructure of cells‚ that is‚ parts smaller than what can be seen with a light microscope‚ otherwise known as organelles and their functions. Light microscopes had been developed to a point where the quality of the lenses was not limiting the detail in the image‚ the main

Polarized light are those that are vibrating in one direction- in a single plane such as up and down. Those that are vibrating in more than one direction -- in more than one plane such as both up/down and left/right -- are called unpolarized light. Generally‚ unpolarized light can be considered to be vibrating in a vertical and a horizontal plane. To polarize light‚ one can transmit the light through a polariod filter which will only allow light of single polarity to pass. The resulting light will
