Matthias Jakob Schleiden (German: [maˈtiːas ˈjaːkɔp ˈʃlaɪdn̩]; [1] [2] 5 April 1804 – 23 June 1881) was a German botanist and co-founder of cell theory, along with Theodor Schwann and Rudolf Virchow.
In his 1838 publication on phytogenesis, Schleiden declared the cell as the fundamental unit of all plants and identified the cell nucleus, which was discovered in 1831, as an essential factor in plant growth. [6] The cellular theory of plant organism structure brought about a reorientation in botany. Before this, botany was primarily focused ...

The book has been called "a conspicuous milestone in nineteenth century biology" by Karl Sudhoff and "epoch making" By Francis Münzer. [3] The book, originally published in German, was translated to English in 1847 by Henry Spencer Smith in an edition that also contained the treatise Phytogenesis, by Matthias Schleiden. [4]
In the Bible outside of Genesis, the term "tree of life" appears in Proverbs (3:18; 11:30; 13:12; 15:4) and Revelation (2:7; 22:2,14,19). It also appears in 2 Esdras and 4 Maccabees , which are included among the Jewish apocrypha. According to the Greek Apocalypse of Moses, the tree of life is also called the Tree of Mercy.
From these conclusions about plants and animals, two of the three tenets of cell theory were postulated. 1. All living organisms are composed of one or more cells 2. The cell is the most basic unit of life. Schleiden's theory of free cell formation through crystallization was refuted in the 1850s by Robert Remak, Rudolf Virchow, and Albert ...
Crucial to this doctrine are the ideas that life comes from non-life and that no causal agent, such as a parent, is needed. Supposed examples included the seasonal generation of mice and other animals from the mud of the Nile , the emergence of fleas from inanimate matter such as dust, or the appearance of maggots in dead flesh.
Demonstration of the cellular composition of all organisms, with each cell possessing all the characteristics of life, is attributed to the combined efforts of botanist Matthias Schleiden and zoologist Theodor Schwann (1810–1882) in the early 19th century, although Moldenhawer had already shown that plants were wholly cellular with each cell ...
