Question

All of the following statements are true regarding the "cell theory" except

• A. All living things are made up of cells
• B. Cells are the smallest structural and functional unit of life
• C. Cell comes only from pre-existing cells
• D. All cells arise spontaneously

Answer 1

The correct option is D All cells arise spontaneously

For centuries people accepted the "spontaneous generation" of life from inanimate matter. When this long-standing myth was finally dispelled in the mid-1800's by Pasteur with his swan neck flask experiments, it became clear that all life must arise from pre-existing life — via a process of reproduction.
