Assess the impact of technology on the development of cell theory. In particular, include the development of the microscope and give evidence where possible.

Since Galileo began using a rudimentary compound microscope in 1609, altogether new ranges of objects not known to even exist were discovered from that basic piece of technology. The microscope played the key role in discovering cells, and as it advanced with technology, so too did the cell system. In 1665, scientist Robert Hooke employ a microscope to look at slices of bobber. He observe that the cork was divided up into hundreds of tiny little compartments that he named cells. Hooke was the premier person to acknowledge cells, and this was when the cell possibility began. In 1758 a spectacle shaper John Dollard, patented an almost all achromatic lens system that made colour-free refracting telescopes possible. Later on in 1821 Giovan Battista Amici attempted to append the resolution of the microscope, and invented the oil preoccupancy techniques that brought microscopes to their greatest resolution, onlyowing far more(prenominal) detailed scientific work to progres s. A French microscopist Henri Dutrochet in 1824, proposed that all organisms are made of cells. thither was general support of this theory in the scientific community, as experiments undertaken watch disclosemed to point towards this. However, a carve up of pack still believed in self-produced multiplication. It wasnt until 1864 that Louis Pasteur dispelled the theory of spontaneous generation through an experiment with microbes on dust particles beseeming lodged in cheat on necked flasks. Air entered the flask solely no microbes grew in the boiled broth inside the flasks. Pasteur develop heat sterilization techniques and used the most powerful kind of compound microscope of the daylight to look at the bacteria. Although difficult to see, Pasteur could see that they were multiplying. His discovery was chief(prenominal) in disproving the spontaneous generation theory of cells, in which cells were created out of nothing. In 1831 a British botanist Robert cook notice what... !
