All cells arise from pre-existing cells.

All living organisms are composed of one or more cells.

Verified step by step guidance
1
Begin by understanding the three principles of cell theory, which are fundamental to biology.
The first principle states that all living organisms are composed of one or more cells. This highlights the universality of cells in life forms.
The second principle asserts that the cell is the basic unit of structure and organization in organisms, emphasizing the role of cells as building blocks.
The third principle explains that all cells arise from pre-existing cells, which underscores the continuity of life through cell division.
Identify the statement that contradicts these principles: 'Cells can spontaneously generate from non-living matter.' This idea is not part of cell theory and was disproven by scientific experiments, such as those conducted by Louis Pasteur.
