    Impact of Light and Electron Microscope on Cell Theory

    With the development of the light microscope many scientists were able to view microscopic objects such as cells. The first to accomplish this was Robert Hooke when he used a light microscope to observe a thin slice of cork. Hooke observed that the cork was made of tiny structures of which he called cells. Hooke was in fact looking at the cell walls of dead plant cells that make up the cork. After Hooke, a Dutch scientist named Anton van Leeuwenhoek used the light microscope to observe living cells inside stagnant rain 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 come from pre-existing cells. Staining techniques later on enabled scientists to observe the cells organelles such as Robert Brown and his discovery of the cell nucleus.…

    Eukaryopolis: Animal Cell City

    Well, the answer to that is Robert Hooke in 1665 using a beta version of what we today call a microscope. While Hooke may have been the first one to discover cells, he was not correct on what went on inside of a cell. Hooke thought the cells looked like bare, Spartan monks with not a whole lot going on inside. This couldn’t have been further from the truth. Cells in fact are just the opposite. For something so very small they are very busy.…

    Cell Theory and Knowledge and Understanding

    The technological advancements, in the scientific field, have opened opportunities for scientists to accumulate knowledge and understanding of the cell theory and have thus provided justification to the living organisms that exist. Notably, prior to the proposal of the cell theory, limited knowledge and understanding of what humans comprised of was evident and thus the theory of spontaneous generation was brought forth. This theory, which has been disproved by Virchow in 1855, suggests that living matter arouses spontaneously from non-living matter. As a consequence of limited technology, many people believed this theory as technological inventions like the light compound microscope, which showed life, were non-existent at the time. Evidently, in 1665, Robert Hooke, an English scientist, invented his own compound microscope and observed the cellular nature of the cork. The topic of cells was brought forth and from this moment, in 1674 Leeuwenhoek viewed microscope ' animalcules' and in 1838, Schleiden and Schwann produced the cell theory, stating that all living things are made of cells and cells are the basic unit of organisms. Moreover, the technological introduction of stains were developed and assisted scientists to efficiently see cells and their internal structures. This staining technique, as a result of technology, created a contrast between the transparent material and its background, presenting a clear image of the cell. Therefore, through the technology advancement in staining techniques, the processes of the cells and nuclear division of the cell were visible. Significantly, towards the end of the 19th century, compound light microscopes had been developed to a point where the resolving power of microscopes was diminishing, with difficulty in separating objects. The next scientific breakthrough was evident as a result of the…

    The book draws its name from the first essay, "The Lives of a Cell," in which Thomas offers his observations on ecology and the role of cellular activity. He writes that the "uniformity of the earth's life, more astonishing then its diversity, is accountable by the high probability that we derived, originally, from some single cell, fertilized in a bolt of lightning as the earth cooled" (3).…

    Technology and Cell Theory

    In 1663, Robert Hooke, proposed that organic matter was composed of what he called, cells. He was able to view these cells as he used a simple microscope, which allowed him to see what organisms were composed of. The advent of the simple microscope however was not enough for the scientific community to accept this theory, as the images had low resolution. So between 1674 – 1683, Anton Van Leewenhoek developed a microscope that allowed for greater magnification, of upto 200x. This increased magnification and resolution has allowed him to view bacteria, and this time the scientific community accepted the findings due to the resolution of the images. In 1838, German scientists, Theodor Schwann and Mattibias Schleiden, discussed the similarities in the animal and plant cells that they were observing through their compound light microscopes. They observed that both cells contained nuclei, and this provided them with the basis of their cell theory. The availability and magnification of microscopes made this discovery possible, and is what provided two of the 3 main points of the cell theory. The final part of the theory, that states that all cells come from pre existing cells, was proposed by Rudolf Virchow. Through his microscope, he was able to witness and name the process of mitosis, which is how cells reproduce.…
