Q. Which of the following is NOT a component of the cell theory? (2018)
A.
All living things are composed of cells
B.
Cells are the basic unit of life
C.
All cells arise from pre-existing cells
D.
Cells can arise spontaneously from non-living matter
Solution
The cell theory states that all living things are composed of cells, cells are the basic unit of life, and all cells arise from pre-existing cells. Spontaneous generation is not part of the cell theory.
Correct Answer:
D
— Cells can arise spontaneously from non-living matter
