Impact of Light and Electron Microscope on Cell Theory

With the development of the clear microscope many scientists were fitted to trance microscopic objects such(prenominal) as cells. The first to accomplish this was Robert Hooke when he employ a light microscope to wield a thin stroke of dock. Hooke respectd that the cork was made of tiny structures of which he c whollyed cells. Hooke was in circumstance looking at the cell w altogethers of dead gear up cells that make up the cork. After Hooke, a Dutch scientist named Anton new wave Leeuwenhoek used the light microscope to observe spirited cells inside dead(a) fall water. This then developed the cell theory in which all living things were made of cells, cells are the smallest units of life and that all cells sire from pre- hold outing cells. Staining techniques later on modifyd scientists to observe the cells organelles such as Robert Brown and his discovery of the cell nucleus. The asylum of the electron microscope in the 1930s also had a Brobdingnagian electric shock on the schooling of cells. An electron fires a ship of electrons at the tar baffle which is used to illuminate the specimen and change go outing on a fluorescent covering or photographic plate. The electron microscope enabled scientists to view cells at a oft larger magnification at a laid-back cloture. This enabled them to view many cell organelles such as ribosomes to be ocular as they are too small to be viewed with a light microscope. Although the electron microscope could view cells at a high resolution, it exposed the cells to a vacuum and could therefore only be used to observe dead cells and not living cells. The unveiling of both the light and electron microscope had a melodramatic issuing on the development of the cell theory and the study of cells altogether. Microscopes enabled cells to be viewed and studied in order to explain their functions and structures.

The mind of the human, set and living organism anatomy was then modify and scientists were then able to answer certain questions concerning the structure of plants, animals and humans. The light and electron microscope enabled scientists to observe and study the smallest units of life. The light microscope enabled the viewing of live cells although its magnification and resolution is limited, while the electron microscope enabled the viewing of cells at a higher magnification and resolution but is cut back to dead cells. Without microscopes to view cells, the cell theory would not exist and many questions concerning plant, animal and human anatomy would be left over(p) unanswered.
