What does the cell theory state?

The cell theory is a fundamental concept in biology that highlights the importance of cells in the study of life. According to this theory, two of the central tenets are that cells are the smallest living units of life, and all cells arise from pre-existing cells.

The first component, stating that cells are the smallest living units, emphasizes that all biological processes necessary for life occur within cells. This concept is crucial because it establishes cells as the basic building blocks of all organisms, whether unicellular or multicellular.

The second component of the cell theory asserts that all cells arise from pre-existing cells through processes like cell division. This principle indicates that life does not spontaneously generate but rather is propagated through existing cellular structures, reinforcing the continuity of life.

Both of these components form a cohesive understanding of the nature of life, thereby reaffirming why the answer indicating that both statements are correct is the most accurate.
