What human inventions contributed to the emergence and development of the science of cytology?

First, remember that cytology studies living cells. This science was able to begin to develop only after the invention of the microscope. Galileo is believed to be the inventor of the first microscope, although it might not have been him. But this microscope was not very good. He did not allow a good look at the cells. Only thanks to Robert Hooke was it possible to examine a living cell. He perfected the microscope and was the first to describe a living cell, gave it the definition of a “cell”, examined and described the female ovum, as well as the male sperm.
