The Discovery of Cells 7.1 The History of the Cell Theory The invention of microscopes assignment it possible for scientists to view and study prison carrels. Cells argon the canonic 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, confused 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 on a lower floor a compound microscope. Thinking the small shapes he truism looked homogeneous small rooms, he called them jail cells. By he 1800s, microscopes had been modify allowing scientists to make other heavy observation. First, Robert Brown, a Scottish scientist, spy that cells had an important inner compartment, the pith (NEW klee us). Then, Rudolf Virchow figured out that the nucleus controls the cells activities. Later, deuce Germ an biologist, 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 sensation 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 be made up of one or more cells. Cells are the basic units of structure and figure out in living things. All cells come over cells. H ow do microscope help scientist learn most ! cells? In the 1930s and 1940s, microscopes were improved. negatron microscope allowed scientists to magnify an object up to 500 000 times using a beam of electrons instend of a beam of light. A scan 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
