Antoni Van Leeuwenhoek
In his microscope he saw motile particles and solidified that these particles were indeed living organisms. Which he gave the name "animalcules" This is very important because it contributed to the first evolution in anything cell related -
Micrographia Is Published
Microgarphia was published by Hooke it was first important work devoted to microscopical observation. It Showed what the microscope could mean for naturalists. This was important because it was helpful to scientists who studied cells. -
Period: to
Nucleus
The first person to recognize the nucleus was Robert Brown as an essential constituent of living cells. Brown recognized the general occurrence of the nucleus in these cells and apparently thoughts of the organization of the plant in terms of cellular constituents, which greatly contributed to Matthaias jakob schieden's story -
Period: to
Theodor Schwann
Theodor schwann stated that "the elementary parts of all tissues are formed of cells" There is one universal principle of development for the elementary parts of organisms. This is important because this principle is in the formation of cells -
Achromatic Microscope
The 1830's achromatic microscopes were made by joseph jackson lister., This also allowed more precise histological observations. This is important because it improvements were also made in tissue preservation and treating techniques. -
Matthias Jakob
Matthias Jakob schieden suggested that every structual element of plants is composed of cells of their product. This was denived from Brown's discovery of nucleus in a plant cell. This is important because greatly contributed to Theodor schiwann theory and discovery about cells in animals -
Pre exisiting Cells
Rudolf Virchow and albert kolliker showed that cells are formed through scission of pre-exiting cells. This is important because this because the basisi ofthe theory of tissue formation -
Period: to
Neuron Theory
Santiago Ramon Y Cajal became the main supporter and indefatigable champion of the neuron theory. This is important because the neutroanatomical investigations contributed to the foundations of the basic concepts of modern neuroscience. -
Oil Imersion Lens
The official introduction of the oil imerson lens happened in 1870 by Thomas Ross, suggested by Van Heurck. This is important because of the development of the microtone technique and the use of new fixing methods and dyed greatly improved the efficiency of microscopy -
Salamander Chromosome
Walther flemming observed the longitudinal splitting of salamander chromosomes during metaphase and established that each half chromosomes moves to the opposite pole of the mitotic nucleus. This is very important because it provides alot of evidence of the deep unity of the living world.
