The Evolution of the Cell Theory

The Evolution of the Cell Theory

Since the beginning of humanity, science has been a developing topic full of mystery and questions. These questions might be as small as why closet doors close easier during the winter compared to the summer, and as big as how the universe was made. There are numerous topics in science such as chemistry, biology, and physics each of which have their own questions to be answered. They each have their own theories which have been developing since they began; but what is a theory? Well, according to Merriam-Webster’s Dictionary, a theory is “an idea or set of ideas that is intended to explain facts or events.” Theories are a way of providing one straight explanation for a wide topic. Without theories, humanity would have to keep explaining a question without having an explanation for things that relate to it. However, theories are not only in the topic of science. There are mathematical, musical, and theories for pretty much every topic in this world. Keep in mind that a theory is not a law. For example, a famous scientifically theory most people have heard of is the Big Bang Theory. This theory is an effort to explain what happened at the very beginning of our universe; however, this theory explains other theories which in turn explain other theories making an enormous chain of theories that become more specific as you go down the chain. The key word in that is it is an effort to explain something. Theories are constantly developing and never really stop unit everything has been overlooked. Another famous theory falls in the scientific topic of Biology; the Cell Theory. This theory refers to the idea that cells are the basic unit of structure of all living things, and it backs that up with three mor...

...over the nucleus. After all these discoveries, Henri Dutrochet finally steps in and makes the ultimate connection between animal and plant cells. He stated that the cell was not only structural, but also a physiological unit; "It is clear that it constitutes the basic unit of the organized state; indeed, everything is ultimately derived from the cell", Henri stated. Durtrochet also proposed that new cells arrived from old cells, a view that was previously stated by Francois Raspail.
