Unified cell theory
- By the late 1830s, botanist Matthias Schleiden and zoologist Theodor Schwann were studying tissues and proposed the unified cell theory. The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.

Matthias Jakob Schleiden (German: [maˈtiːas ˈjaːkɔp ˈʃlaɪdn̩]; 5 April 1804 – 23 June 1881) was a German botanist and co-founder of cell theory, along with Theodor Schwann and Rudolf Virchow. He published some poems and non-scientific work under the pseudonym Ernst.

M.J. Schleiden. Matthias Jakob Schleiden (1804 - 1881) was Professor of botany at the University of Jena and is best known as one of the foundational architects of the cell theory. Schleiden was also an early evolutionist.

Explain the key points of cell theory and the individual contributions of Hooke, Schleiden, Schwann, Remak, and Virchow. Explain the key points of endosymbiotic theory and cite the evidence that supports this concept. Explain the contributions of Semmelweis, Snow, Pasteur, Lister, and Koch to the development of germ theory.
Mar 2, 2018 · Within a few years, sufficient empirical evidence had accumulated to abandon Schleiden’s concept of cell formation. Because of technical difficulties, it took much longer to accumulate precise observations of animal cell formation. Robert Remak (1815–1865) proposed the first explicit unifying theory of cell division in both plants and animals.
The first cell theory is credited to the work of Theodor Schwann and Matthias Jakob Schleiden in the 1830s. In this theory the internal contents of cells were called protoplasm and described as a jelly-like substance, sometimes called living jelly.
