What is the contribution of Schleiden and Schwann in the field of cytology?
Schwann, Theodor (1810–82) A German physiologist who, in collaboration with M. J. Schleiden, proposed the cell theory (and coined the term), according to which all plant and animal tissues are composed of cells, and within an individual organism all the cells are identical (see also VIRCHOW, RUDOLF).
Who discovered cytology?
The earliest phase of cytology began with the English scientist Robert Hooke’s microscopic investigations of cork in 1665. He observed dead cork cells and introduced the term “cell” to describe them.
How did Matthias Schleiden discover the cell theory?
In 1838 Matthias Schleiden had stated that plant tissues were composed of cells. Schwann demonstrated the same fact for animal tissues, and in 1839 concluded that all tissues are made up of cells: this laid the foundations for the cell theory. Schwann also worked on fermentation and discovered the enzyme pepsin.
What is Robert Hooke contribution to the cell theory?
English scientist Robert Hooke published Micrographia in 1665. In it, he illustrated the smallest complete parts of an organism, which he called cells. theory that all organisms are made of cells, which are the basic structural units of life.
What is the contribution of Rudolf Virchow in cell theory?
Virchow used the theory that all cells arise from pre-existing cells to lay the groundwork for cellular pathology, or the study of disease at the cellular level. His work made it more clear that diseases occur at the cellular level. His work led to scientists being able to diagnose diseases more accurately.

What contributions did Matthias Schleiden discover?
In 1838, Matthias Schleiden, a German botanist, concluded that all plant tissues are composed of cells and that an embryonic plant arose from a single cell. He declared that the cell is the basic building block of all plant matter.
What did Robert Hooke contribute to the cell theory?
The invention of the microscope led to the discovery of the cell by Hooke. While looking at cork, Hooke observed box-shaped structures, which he called “cells” as they reminded him of the cells, or rooms, in monasteries. This discovery led to the development of the classical cell theory.
