Creating Cell Theory. Scientist Matthias Schleiden discovered in 1838, that all plants have cells, which are called plant cells. Theodor Schwannn found that all animals are also made up of cells, which are called animal cells. These are two types of the many different kinds of cells.
By 1838 his methods had led him to propose the cell theory for plants. Schleiden was the first to recognize the importance of cells as fundamental units of life. In his most well-known article, Schleiden described Robert Brown's 1832 discovery of the cell nucleus (which he renamed cytoblast).Schleiden knew that the cell nucleus must somehow be connected with cell division, but he mistakenly believed that new cells erupted from the nuclear surface like blisters.n his most well-known article, Schleiden described Robert Brown's 1832 discovery of the cell nucleus (which he renamed cytoblast).
