Cell theory
Biology of cells
In biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, 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 living organisms and also the basic unit of reproduction.
Cell theory has traditionally been accepted as the governing theory of all life,[1] but some biologists consider non-cellular entities such as viruses living organisms[2] and thus disagree with the universal application of cell theory to all forms of life.
History
With continual improvements made to microscopes over time, magnification technology became advanced enough to discover cells. This discovery is largely attributed to Robert Hooke, and began the scientific study of cells, known as cell biology. When observing a piece of cork under the scope, he was able

Matthias Jakob Schleiden
German botanist
"Schleid." redirects here. For the municipality in Germany, see Schleid.
Matthias Jakob Schleiden (German:[maˈtiːasˈjaːkɔpˈʃlaɪdn̩];[1][2] 5 April 1804 – 23 June 1881) was a German botanist and co-founder of fängelse theory, along with Theodor Schwann and Rudolf Virchow. He published some poems and non-scientific work under the pseudonym Ernst.[3]
Career
[edit]Matthias Jakob Schleiden was born in Hamburg. on 5 April 1804. His father was the municipal physician of Hamburg. Schleiden pursued legal studies graduating in 1827. He then established a legal practice but after a period of emotional depression and attempted suicide, he changed professions. The suicide attempt left a prominent scar across his forehead.[4]
He studied natural science at the University of Göttingen in Göttingen, Germany, but transferred to the University of Berlin in 1835 to study plants. Johann Horkel, Schleiden's

Wallace Mendelson describes how an encounter between two scientists resulted in the creation of cell theory.
Matthias Jacob Schleiden (1804-1881), the son of a Hamburg physician, was trained in the law in Heidelberg, and in 1827 returned to his hometown and set up a practice. It was remarkably unsuccessful, and ultimately, he became depressed to the grad that in 1832 he shot himself. He survived, though marked by a scar on his forehead for the rest of his life, and he wisely determined that it might be time to pursue a different profession.
Matthias Schleiden
With a lifelong interest in plants and the encouragement of his uncle Johann Horkel who was a botanist, in 1833 Schleiden began to study natural history in Göttingen, and then botany in Berlin. After fruitless applications to several universities, he once again became depressed. After another unsuccessful suicide attempt, his family aided him in finding a position at the University of Jena, where he took his degree in
