Document Summary
Hooke ddled with the the rst microscope in the late 1600"s. He discov- ered that cork was formed from little compartments and from the latin word cellula (rooms) the term cell formed. Light microscopy began the eld of cell biology. After an increase in optical strength from the microscopes it became possible to see many more objects. Leuwenhoek was a very passionate scientist devoted to using the microscope to look at anything he could get his hands on. As a result of this incessant hobby, he is famous for many discoveries. 30 nm ribosomes - 200 nm viruses - 6 m red blood cell - 200 m minimum visbility by human. Cell theory: all organisms consist of cells, cells are the basic unit of structure, all cells arise from other cells. Di erent methods of microscopy: light: stains attract/grab certain obgjects within the cell: eg. nucleic acids, uoresence = cyto celetons. 2 lecture 3 - intro to basic chemistry.
