- Matthias Jakob Schleiden (born April 5, 1804, Hamburg [Germany]—died June 23, 1881, Frankfurt am Main, Germany) was a German botanist, cofounder (with Theodor Schwann) of the cell theory. Schleiden was educated at Heidelberg (1824–27) and practiced law in Hamburg but soon developed his hobby of botany into a full-time pursuit.

It may seem obvious now that we, and other living things, are made up of cells. Prior to the 1600s, however, it wasn’t obvious at all, for the simple reason that no one had ever seen a cell up close and personal.
Oct 19, 2023 · From the single cells that make up the most basic organisms to the trillions of cells that constitute the complex structure of the human body, each and every living being on Earth is comprised of cells. This idea, part of the cell theory, is one of the central tenants of biology.
Cells are made of atoms (everything is), but cells are alive and atoms are not, so cells are the basic units of life. Lots of stuff made from atoms is not alive.

Jul 21, 2023 · The cell theory beautifully explains how the human cell body is composed of trillions of cells, each with specific functions. Cells combine to form tissues (e.g., muscle tissue, nerve tissue), which then make up organs (e.g., heart, brain), which further constitute specific organ systems (e.g., circulatory system, nervous system).
Apr 5, 2024 · In his studies, he observed that the different parts of the plant organism are composed of cells or derivatives of cells. Specifically, he observed that “the lower plants all consist of one cell, while the higher ones are composed of (many) individual cells.”

As mentioned in Cell Theory, all living things are composed of one or more cells, cells are the basic unit of life, and that new cells come from preexisting cells. There are many kinds of cells, but generally, they can be classified in two broad groups: prokaryotic and eukaryotic.
All cells only come from other cells (the principle of biogenesis). Cells are the fundamental units of organisms. Today, these tenets are fundamental to our understanding of life on earth. However, modern cell theory grew out of the collective work of many scientists.
