What did Schleiden and Schwann do?
As a professor of botany at the University of Jena, he wrote Contributions to our Knowledge of Phytogenesis (1838), in which he stated that all plants are composed of cells. Thus, Schleiden and Schwann became the first to formulate what was then an informal belief as a principle of biology equal in importance to the atomic theory of chemistry. He also recognized the importance of the cell nucleus, discovered in 1831 by the Scottish botanist Robert Brown, and sensed its connection with cell division .

Why did Schleiden and Schwann apply preformationism to cells?
This theory was applied to cells because cells inherited their forms from earlier cells.

Zeiss established a factory in Jena and continued to work on microscopes and microscope lenses. With the help of these more powerful and advanced lenses, Schleiden and Schwann developed their cell theory through microscope observation and experiments.

Matthias Jakob Schleiden came into the world on April 5, 1804 in the German city of Hamburg. His father was a prestigious local doctor and his uncle was the botanist Johan Horkel. His influence was essential for Schleiden to begin to love the study of plants.
What did Schleiden do?
Although he studied law, Schleiden devoted most of his life to botany. In this field he opposed the study method of his time, since according to himself he affirmed, he was only dedicated to describing and naming the different plants.
What did Schleiden do when he began working in botany?
When he began working in botany, Schleiden distinguished himself by criticizing his colleagues.For the scientist, most botanists were wasting time arguing over how to name plant species, while he sought to redefine the discipline. To do this, he intended to use the most modern methods to investigate the functions and composition of plants.
What city did Schleiden work in?
When Schleiden arrived in Berlin, this city had become the workplace of well-known naturalists such as Robert Brown or Alexander von Humboldt. At that time, several laboratories dedicated to scientific research had been opened.
Why did Schleiden believe that plants grow?
At first, Schleiden claimed that plant growth was due to the generation of new cells starting from the nuclei of old ones.
Where did Schleiden go to study?
It was during the time he was recovering from his physical injury and depression due to his lack of success in law that Schleiden decided to turn his life around. Thus, in 1833 he moved to Göttingen to study natural sciences. After this he moved to Berlin.

Despite all that success, Schleiden suffered from problems such as fatigue, depression and anxiety. The latter caused him to submit his resignation and dedicate himself to traveling.
Where did Matthias Schleiden go to college?
Matthias Schleiden was born in Hamburg, Germany, in 1804. He did not originally pursue his interest in botany; instead, he studied law at Heidelberg University from 1824 to 1827 (no doubt influenced by his wealthy family). After graduation, Schleiden became a barrister in Hamburg, but he soon grew dissatisfied with his legal practice and suffered a deep depression that culminated in his attempted suicide. He abandoned the profession altogether in 1831 and returned to college to pursue his real interests--botany and medicine. After his graduation, Schleiden became professor of botany at Jena University. Instead of spending his time classifying plants, however, he preferred to observe their development using the microscope because he felt that was the only way plants could be studied.
Who expanded Schleiden's cell theory?
In 1839, Theodor Schwann would expand Schleiden's cell theory to include the animal world, establishing cell theory as the fundamental concept in biology. Schleiden included this article and others in a botany textbook--one that introduced new teaching methods which would dominate the instruction of botany for years.
What did Schleiden believe about the cell nucleus?
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. Even so, he made other accurate observations about plant cells and cell activity and his conclusions marked the beginning of plant cytology.
Who was the first person to recognize the importance of cells as fundamental units of life?
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).

Who was the first scientist to explain the cell theory?
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 included this article and others in a botany textbook--one that introduced new teaching methods which would dominate the instruction of botany for years. His approach to educating students was very different, and his liberal views often put him at odds with other scientists. However, his great abilities and his introduction of improved techniques earned him the title "reformer of scientific botany."
