Experiments Francesco Redi Rotting meat was placed in two experimental jars and two control jars. By Placing Cloth over the experimental jars of rotting meat‚ Redi was able to test his hypothesis that only flies can produce more flies. Over time‚ the control jars were filled with maggots and flies. However‚ the experimental jars were free of insects. Demonstrates the maggots only appear if flies land on meat.

other ideas like it were believed and accepted during that time‚ which was not too long ago. <br> <br>The first serious attack on the idea of spontaneous generation was made in 1668 by Francesco Redi‚ an Italian physician and poet. At that time‚ it was thought that maggots arose spontaneously in rotting meat. Redi believed that maggots developed from eggs laid by flies after observing that they had different developmental stages.. To test his hypothesis‚ he set out meat in a variety of flasks‚ some

Contributors to Microbiology Pioneers of Microbiology I. Antonie van Leeuwenhoek (Oct. 24‚ 1632- Aug. 30‚ 1723) A. In 1676 Leeuwenhoek saw tiny organisms in water‚ he was the first man to observe and describe bacteria accurately. He discovered microscopic nematodes‚ blood cells and sperm. He also made over 500 microscopes to view specific objects. B. Microbiology is concerned with the study of all forms of life that are too small to be seen with the naked eye. Antonie’s work

Microbiology is the branch of Biology that deals with the study of microorganisms and how they influence or work with other living organisms. (Satellite Events Enterprises Inc.‚ 1999) In this paper I will discuss the history of Microbiology and specifically the early theory of spontaneous generation. I will discuss three spontaneous generation experiments and explain why it is obsolete in today’s science. History of Microbiology Since Microbiology is the study of microorganisms‚ it is understandable
