Document Summary

First microscope was created by robert hooke -> viewed slices of cork. Antoni van leeuwenhoek, known as the father of microbiology, was the first to observe single-celled organisms. Improved the quality of the microscope lenses (his hobby was playing with glass: nearly 300x magnification became possible, first to view protest, bacteria, blood cells, sperm, banded pattern in muscle cells.

Improved magnification and resolution (needed two lenses: allowed visualization of objects less than 1um. What can we see? (from largest to smallest) cells -> organelles -> molecules -> atoms. Cell theory began in 1833 when botanist robert brown noticed that every plant cell contained a round structure -> the nucleus (kernel) 1838 botanist matthias schleiden determined that all plant tissues are composed of cells: embryonic plants always arose from a single cell.
