The Discovery of Cells 7.1 The History of the Cell Theory The invention of microscopes buckle below it possible for scientists to view and study prison carrells. Cells argon the basic 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, heterogeneous 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 under a compound microscope. Thinking the small shapes he cut looked homogeneous small rooms, he called them booths. By he 1800s, microscopes had been modify allowing scientists to make other heavy observation. First, Robert Brown, a Scottish scientist, find that cells had an important inner compartment, the substance (NEW klee us). Then, Rudolf Virchow figured out that the nucleus controls the cells activities. Later, deuce German bio logist, Matthias Schleiden and Theodore Schwann, did their own experiments and learned that all nutriment 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(a) of the fundamental ideas of the science of biology.

The three main split of the cell theory argon summarized below: all in all living things ar made up of one or more cells. Cells are the basic units of structure and persist in living things. All cells come over cells. How do micros cope 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 apply a beam of electrons instend of a beam of light. A see electron microscope (SEM) lets scientists see a cells three-dimensional shape. A transmitting 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
