These parts were based on a conclusion made by Schwann and Matthias Schleiden in 1838, after comparing their observations of plant and animal cells.
What type of cell did Schleiden study?
German scientists Theodore Schwann and Mattias Schleiden studied cells of animals and plants respectively. These scientists identified key differences between the two cell types and put forth the idea that cells were the fundamental units of both plants and animals.

What if the microscope was not invented?
Without them, we would have no idea about the existence of cells or how plants breathe or how rocks change over time. Our understanding of the world around us would be severely limited – and this is why many scientists see microscopes as the most important scientific instrument there is.

Anton Van Leeuwenhoek was the first person to observe living cells. In 1675, he saw a single celled organism in a drop of pond water. These living things were microscopic and could not be seen without a microscope. By 1800, better microscopes were being made.
What did Rudolf Virchow discover in 1855?
Virchow's greatest accomplishment was his observation that a whole organism does not get sick—only certain cells or groups of cells. In 1855, at the age of 34, he published his now famous aphorism “omnis cellula e cellula” (“every cell stems from another cell”).

Work
- Matthias Jacob Schleiden helped develop the cell theory in Germany during the nineteenth century. Schleiden studied cells as the common element among all plants and animals. Schleiden contributed to the field of embryology through his introduction of the Zeiss microscope lens and via his work with cells and cell theory as an organizing principle of...
Early life and education
- Schleiden was born in Hamburg, Germany, on 5 April 1804. His father was the municipal physician of Hamburg. Schleiden pursued legal studies at the University of Heidelberg in Heidelberg, Germany, and he graduated in 1827. He established a legal practice in Hamburg, but after a period of emotional depression and an attempted suicide, he changed professions. He studied natural …
Life and work
- In Berlin, Schleiden worked in the laboratory of zoologist Johannes Müller, where he met Theodor Schwann. Both Schleiden and Schwann studied cell theory and phytogenesis, the origin and developmental history of plants. They aimed to find a unit of organisms common to the animal and plant kingdoms. They began a collaboration, and later scientists often called Schleiden and …
Academic career
- Schleiden again transferred, this time to the University of Jena in Jena, Germany, where he received his doctorate in botany in 1839. He then worked for the university as a professor in botany and studied a range of topics in which to lecture and publish. In 1844, Schleiden married his first wife, Bertha Mirus, with whom he had three daughters. Mirus died in 1854, and Schleide…
Origins
- Schleiden entered a debate with Giovan Amici, who lived in Italy, in 1842. At the Fourth Italian Scientific Congress in Padua, Italy, Amici presented his observations \"Sulla fecondazione delle piante Cucurbita Pepo\" (On the fertilization of plants Cucurbita Pepo). Schleiden agreed with Amici that the growth of the pollen tube in plants went through the stigma and style, located insi…
Formation
- Schleiden said that when the cytoblast, which later scientists termed the nucleus, reaches its final size, a transparent vesicle forms around it, creating the new cell which then proceeds to crystallize within a formative liquid. He said that cells can only form in a liquid containing sugar, gum, and mucus, or the cytoblastema. The mucous portion condenses into round corpuscles, an…
Research
- Many scientists worked on the crystallization of cells before Schleiden. The claim that cells crystallized inside a primary substance traced back at least to Nehemiah Grew, who studied plants in England during the seventeenth century. Other who studied crystallization in the nineteenth century included François-Vincent Raspail and Charles Robin in France, and Hugo vo…
Controversies
- Schleiden's research on cytogenesis and the free genesis of cells sparked many scientific debates and controversies. Many of these controversies started with Schleiden's criticism of botanists from the early nineteenth century. Schleiden declared himself an enemy of all philosophical speculation, especially speculative botany, because he argued that the botanists should conduc…
Other activities
- Schleiden gave many lectures, often for large audiences, some of which were published, such as 1850's Die Pflanze und ihr Leben (The Plant and Its Life) and 1857's Studien (Studies). In 1850 he became a full professor of botany at the University of Jena. Schleiden left Jena in 1863 to become a professor of anthropology at the University of Dorpat, which later became the University of Tar…
