How did Matthias Schlieden and Theodoer Schwan and Rudolf Virchow contribute to the cell theory?

Answer 1

Matthias Schleiden found that all plants are aggregates of fully individualized, independent separate beings, namely the cells themselves. Theodore Schwann, Schleiden, and Virchow made what is known as the modern cell theory.

Answer 2

They discovered the 3 cell theorys. 1.) All living things are made of cells.

2.) Cells are the smallest unit of all living things.

3.) Cells can only come from existing cells. They also discovered that all plants are made of cells.

Answer 3

In 1838, Theodor Schwann and Matthias Schleiden were enjoying after-dinner coffee and talking about their studies on cells. It has been suggested that when Schwann heard Schleiden describe plant cells with nuclei, he was struck by the similarity of these plant cells to cells he had observed in animal tissues. The two scientists went immediately to Schwann's lab to look at his slides. Schwann published his book on animal and plant cells (Schwann 1839) the next year, a treatise devoid of acknowledgments of anyone else's contribution, including that of Schleiden (1838). He summarized his observations into three conclusions about cells:

The cell is the unit of structure, physiology, and organization in living things.

The cell retains a dual existence as a distinct entity and a building block in the

construction of organisms.

Cells form by free-cell formation, similar to the formation of crystals (spontaneous generation).
