The Discovery of Cells 7.1 The History of the Cell Theory The invention of microscopes pass on it possible for scientists to view and study prison mobile ph aneular telephones. Cells argon the elemental units of invigoration organisms. In the 16oos, Anton van Leeuwenhoek( LAY vun hook) used a ace lens microscope to view bacteria, which until the could not be seen. Later, aggregate sporty microscope used several lenses and could magnify object up to 1500 generation their original size. The scientist Robert Hooke looked at thin slices of cork downstairs a compound microscope. Thinking the small shapes he see looked homogeneous small rooms, he called them cells. By he 1800s, microscopes had been better allowing scientists to make other heavy observation. First, Robert Brown, a Scottish scientist, discover that cells had an important inner compartment, the essence (NEW klee us). Then, Rudolf Virchow figured out that the nucleus controls the cells activities. Lat er, deuce German biologist, Matthias Schleiden and Theodore Schwann, did their own experiments and learned that all live things argon made of iodin or more cells. What is cell possibleness? The environment of Schleiden, Schwann, and other scientists led to the development of what is called the cell theory. It is one of the fundamental ideas of the science of biology.

The three main separate of the cell theory argon summarized below: all in all living things are made up of one or more cells. Cells are the basic units of structure and utilisation in living things. All cells come over cells . How do microscope help scientist learn ! most cells? In the 1930s and 1940s, microscopes were improved. electron microscope allowed scientists to magnify an object up to 500 000 times utilize a beam of electrons instend of a beam of light. A examine electron microscope (SEM) lets scientists see a cells three-dimensional shape. A transmittal electron microscope (TEM) lets scientists see the stucture deep down a cell. Microscope are continually being improved so...If you urgency to get a full essay, order it on our website: OrderCustomPaper.com
