Hooke
Hooke discovered a honeycomb like structure (cells) in a cork slice using a primitive compound microscope. Hooke did not know their real structure or function, and he was the first person to discover that objects were made up of these smaller particles. Therefore he could not have disproved any previous model -
Leeuwenhoek
Leeuwenhoek used a microscope, that he made a fine quality lens for (270x), to describe cells in drops of water. In the water he found motile objects. He said motilitiy is a quality of life therefore these cells were living. He named these cells "animalcules" we now know that they were protozoa and bacteria. Leeuwenhoek was the first person to realize cells were living things. Thus disproving past theories from Hooke about the cells. -
Brown
The term cell nucleus was first used by Brown in 1831, and it was officially published in 1833. Brown was studying over 1700 species of plants in Australia when he began to notice opaque spots in the cells of a collection of orchids. He originally used the term areola to define them. It is believed other scientist had seen the same thing as Brown but he was the first to actually take note of them. Brown disproved previous models by proving that cells were not the smallest living components of -
Schleiden
Schleiden preferred to study plant structure under the microscope. Which he used to discover that the different parts of the plant organism are composed of cells. Thus, becoming the first to formulate what was then an informal belief as a principle of biology equal in importance to the atomic theory of chemistry. Schleiden helped build the general knowledge by teaching people cells are used to build up tissues. So he did not disprove previous models he just added to them. -
Schwann
Schwann became familiar with Matthias Schleiden's microscopic research on plants. Pursuing this line of research on animal tissues, Schwann not only verified the existence of cells, but he traced the development of many adult tissues from early embryo stages. Schwann proposed three generalizations concerning the nature of cells. One animals and plants consist of cells plus the secretions of cells. Two these cells have independent lives, which, Three, are subject to the organism's life. -
Virchow
Virchow accepted the work of Robert Remak and proposed that all cells are formed by the division of previously existing cells. Virchow also thought of the idea that diseases do not affect an entire organism but are instead localized to certain groups of cells. Virchow disproved the previous belief in the theory of spontaneous generation by proving that cells must come from other previously existing cells. -
Schwann Two
Schwannadded on to the previous theory that only plants were made up of cells through his discoverey that animals were made up of cells along with plants
