who discovered cells divide to make new cells

title: August Weismann text: during the second half of the 19th century. This was the time that the mechanisms of cell division began to be understood. Eduard Strasburger, Walther Flemming, Heinrich von Waldeyer and the Belgian Edouard Van Beneden laid the basis for the cytology and cytogenetics of the 20th century. Strasburger, the outstanding botanical physiologist of that century, coined the terms nucleoplasm and cytoplasm. He said "new cell nuclei can only arise from the division of other cell nuclei". Van Beneden discovered how chromosomes combined at meiosis, during the production of gametes, and discovered and named chromatin. Walther Flemming, the founder of cytogenetics, title: Robert Remak text: Robert Remak Robert Remak (26 July 1815 – 29 August 1865) was a Jewish Polish-German embryologist, physiologist, and neurologist, born in Posen, Prussia, who discovered that the origin of cells was by the division of pre-existing cells. as well as several other key discoveries. According to historian Paul Weindling, Rudolf Virchow, one of the founders of modern cell theory, plagiarized the notion that all cells come from pre-existing cells from Remak. Remak had reached the conclusion after observing red blood cells from chicken embryos in various stages of division. He then confirmed that the phenomenon existed in the cell of title: Mitosis text: formation of new cells "in their interior" was a general law for cell multiplication in plants, a view later rejected in favour of Mohl model, due to contributions of Robert Remak and others. In animal cells, cell division with mitosis was discovered in frog, rabbit, and cat cornea cells in 1873 and described for the first time by the Polish histologist Wacław Mayzel in 1875. Bütschli, Schneider and Fol might have also claimed the discovery of the process presently known as "mitosis". In 1873, the German zoologist Otto Bütschli published data from observations on nematodes. A few years later, he title: Cell theory text: Cell theory In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction. With continual improvements made to microscopes over time, magnification technology advanced enough to discover cells in the 17th century. This discovery is largely attributed to Robert Hooke, and began the scientific study of cells, also known as cell biology. Over a century later, title: Samuel Weiss text: Calgary in 1988. In 1985 Dr. Weiss and Fritz Sladeczek discovered the metabotropic glutamate receptor, currently an extremely important area of research for neurological disorders. Dr. Weiss was appointed Assistant Professor and MRC Scholar at The University of Calgary in 1988. In 1992, while working at the University of Calgary, Dr. Weiss and graduate student Brent Reynolds found cells in the brains of fetal and adult mice that divided to produce new cells. They claimed that they successfully isolated stem cells and got them to divide and multiply in a lab dish. The success of this experiment suggested that stem
