Which set of statements best summarizes the main points of classical cell theory?
A
All living organisms are composed of one or more cells; the cell is the basic unit of structure and function in living things; all cells arise from pre-existing cells.
B
Energy is produced only in mitochondria; cells can arise spontaneously from nonliving matter; all cells are the same size and shape.
C
All cells contain a nucleus; all organisms reproduce only sexually; all traits are inherited solely through proteins.

Verified step by step guidance1
Identify the core principles of classical cell theory, which are foundational concepts in cell biology.
Recall that classical cell theory states: (1) all living organisms are composed of one or more cells, (2) the cell is the basic unit of structure and function in living things, and (3) all cells arise from pre-existing cells.
Evaluate each given statement set against these three principles to determine which one aligns correctly with classical cell theory.
Eliminate options that contain incorrect or outdated information, such as spontaneous generation, all cells being the same size and shape, or traits inherited solely through proteins.
Select the statement set that accurately summarizes the main points of classical cell theory based on the three core principles.
