The History of Cell Theory

As we all probably know today, every single living being is made up by cells – the building blocks of life. As much as we would like to take this fact for granted, we cannot help but acknowledge and remember the works and discoveries of earlier scientists which all contributed to our today's understanding of the cell theory. The cell theory being; all living things are composed of one or more cells, cells are organisms' basic units of structure and function, and cells only come from existing cells. Their discoveries lead to the development of inventions necessary to induce further research in the area which resulted in the creation of devices such as the microscope.

Robert Hooke
Robert Hooke was probably the greatest experimental scientist of the seventeenth century. He was able to observe cells through studying thin slices of cork which was probably one of his most famous discoveries. He discovered plant cells, and in those he saw what today we know as ‘cell walls'. Hooke was, in fact, the person who first gave them the name of ‘cells' as those box-like cells of cork reminded him of the cells in a monastery. After discovering this in cork slices, he moved on to observing wood and other plants in which he also realized were made up of cells. Further into this, he reported to have discovered "little animals" which we know today as bacteria and protozoa and was able to prove his findings which opened the way for other scientists to pursue their studies in the same matters. He found much difficulty with Anton van Leeuwenhoek's simple microscopes although they conducted clearer images than his own microscope which therefore set to making his own compound microscope which prompted the creation and development of newer and improved microscopes.

His discoveries supported the cell theory because he was amongst the first people to have discovered and partially understood them and given them the name which we still use today. He noticed

    Cell Theory In biology, cell theory is a scientific theory that describes the properties of cells, the basic unit of structure in every living thing. The initial development of the theory, during the mid-17th century, was made possible by advances in microscopy; the study of cells is called cell biology. Cell theory states that new cells are formed from pre-existing cells, and that the cell is a fundamental unit of structure, function and organization in all living organisms. It is one of the…

    Portfolio The Cell and Cell Theory [pic] The cell The word cell comes from the Latin word “cellula”, which means a small room. The cell is the smallest unit of a living organism, also known as “the building block of life”. Every living organism is consisted of a cell. There are bacteria (unicellular organisms), and multicellular organisms. There are different types of cells, prokaryotic and eukaryotic cells. All cells come from preexisting cells. “Every cell is self-maintaining;…

    Cell Structure - Cell Organelles 1. What is cell theory? Cell theory asserts that the cell is the constituent unit of living beings. Before the discovery of the cell, it was not recognized that living beings were made of building blocks like cells. The cell theory is one of the basic theories of Biology. 2. Are there living beings without cells? Viruses are considered the only living beings that do not have cells. Viruses are constituted by genetic material (DNA or RNA) enwrapped by a protein…

    The Cell Theory The Cell Theory, formed by Anton van Leeuwenhoek, Robert Hooke, Matthias Schleiden, Theodore Schwann, and Rudolf Virchow, refers to the idea that cells are the basic unit of structure in every living organism. The theory justifies three principles: all living organisms are composed of one or more cells; the cell is the most basic unit of structure, function, and organization in all organisms; and all cells come from pre-existing, living cells. The formation of the cell theory started…

    The CELL THEORY, or cell doctrine, states that all organisms are composed of similar units of organization, called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin's theory of evolution (1859), Mendel's laws of inheritance (1865), and the establishment of comparative biochemistry (1940). Ultrastructural research and modern molecular biology have…

    background knowledge relating to the current cell theory, the differences between prokaryotes and eukaryotes, and the structures and functions found within cells. Once this knowledge is known, a person is then able to give their opinion in the debate. In the 1800s, the cell theory was developed. This theory states that cells are found in all living things making them the basic units of life and that all cells come from other cells. In order to be classified as a cell, the object in question must be able…

    Weismann, who noted that two cell divisions were necessary to transform one diploid cell into four haploid cells if the number of chromosomes had to be maintained. In 1911 the American geneticist Thomas Hunt Morgan observed crossover in Drosophila melanogaster meiosis and provided the first genetic evidence that genes are transmitted on chromosomes. The term meiosis was introduced to biology by J.B. Farmer and J.E.S. Moore in 1905 Meiosis i/maɪˈoʊsɨs/ is a special type of cell division necessary for…

Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, they also serve as an internal repair mechanism inside many tissues, dividing without…
