GENERAL HISTOLOGY

Detailed explanation-1: -Matthias Jacob Schleiden was a German botanist who, with Theodor Schwann, cofounded the cell theory . In 1838 Schleiden defined the cell as the basic unit of plant structure, and a year later Schwann defined the cell as the basic unit of animal structure.

Detailed explanation-2: -In 1838, German scientist Matthias Schleiden concluded that all plants are made of cells. The next year Theodor Schwann, another German, concluded that all animals were also made of cells.

Detailed explanation-3: -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.

Detailed explanation-4: -The Cell Theory was first given by M.J Schleiden and Theodor Schwann in 1839. It states that all the living beings whether plants or animals are composed of cells that are from pre-existing cells.

Detailed explanation-5: -Two scientists who contributed to the cell theory were Theodor Schwann and Mattias Schleiden. Their work identified the key differences between plant and animal cells. Schwann’s studies on the notochord led him to determine that plants and animals were made of cells and cell products.
