What does the Cell Theory state about cells?

The Cell Theory is a fundamental principle in biology that outlines key aspects of cellular life. Specifically, it posits that all living organisms are composed of cells, and additionally, that all cells arise from preexisting cells. This emphasizes the continuity of life through cellular reproduction, where existing cells divide to produce new cells, thereby maintaining the life cycle.

This understanding has significant implications in biology, as it underscores the role of cells as the basic unit of life, responsible for structure, function, and the processes necessary for living organisms. Recognizing that all life forms, regardless of complexity, share this cellular composition reinforces the interconnected nature of life on Earth.

Other options present ideas that do not align with the foundational concepts of the Cell Theory. The notion that all cells are identical in structure oversimplifies the vast diversity of cell types and functions across different organisms. The idea that cells are formed from inorganic matter misrepresents the biological origins of cells, which arise from existing biological entities rather than non-living substances. Lastly, the claim that all cells are capable of photosynthesis excludes many cell types that do not perform this function, such as those found in animals and fungi. Therefore, the correct answer encapsulates the essential premises of the Cell Theory accurately.
