Question

The founder of cell theory was
1. Wolf
2. Rudolf Virchow
3. Myen, Von Moll and Raspail
4. Schleiden and Schwann

Answer 1

Correct Answer - Option 4 : Schleiden and Schwann

Explanation:

The cell theory was founded by Schleiden and Schwann

• Matthias Schleiden was a German botanist who examined a large number of plants and observed that all plants are composed of different kinds of cells that form the tissues of the plant.
• Theodore Schwann was a British Zoologist who studied different types of animal cells and reported that cells had a thin outer layer which is today known as the plasma membrane’. He also concluded, based on his studies on plant tissues, that the presence of a cell wall is a unique character of the plant cells.
• Schleiden and Schwann together formulated the cell theory

​ 

• Rudolf Virchow gave the concept of Omnis cellula - e - cellula which means new cells arise from the pre-existing cells. 
• He modified the hypothesis of Schleiden and Schwann to give the cell theory a final shape. Cell theory as understood today is:

1. All living organisms are composed of cells and products of cells.
2. All cells arise from pre-existing cells.
