June 23, 1881 (May 27), Government House, the death of German biologist, founder of the cell theory Schleiden.


Schleiden (1804.4.5-1881.6.23) German botanist, one of the founders of the cell theory. Born in Hamburg, died in Frankfurt. 1824 to 1827 studying law in Heidelberg, and lawyer in Hamburg. The attack has a keen interest in botany learning botany, graduated in 1831 from the University of Jena. 1850, he was appointed professor of botany at the University of Jena. In 1838, he published the famous "plant occurred '. The cell theory Engels hailed the three major discoveries of natural science in the 19th century, played a huge role in promoting the development of the biological sciences. Schleiden also recognize the importance of the nucleus, and observed the nucleus and cell division. He also described the movement of the active substance in the cell, that we are talking about protoplasm Hustle movement. He is the first to accept the the German biologist one of Darwin's theory of evolution. (History TodayOnHistory.com)
1839, from the process of the formation mechanism of the cells and the development of life, further improve the cell theory by Schleiden established. Published the "structure and growth of the plants and animals similarity microscopy study, cell theory of Schleiden's successful introduction of zoology, establish uniform cell theory in biology.
establish cell theory, although Schleiden and Schwann already have the basis of this experiment was found inside the cell structure, but the more they rely on their natural philosophical thoughts guided by the theory exploration. Therefore, some of the basic content of the doctrine, such as the formation of the cell itself, at the time they did not receive sufficient experimental evidence. Schleiden that the new cells are generated from the nucleus of the old cells; Schwann that the new cells are generated from the crystallization process of the organic matter in the old nucleus. Shortly after they put forward this theory, this problem is the famous German microscopic anatomist von Moore found cell mitosis this new experimental facts correct.
