Why is the cell theory still accepted today?

All living things are made up of one or more cells, according to cell theory: 1. The smallest living unit is a cell; we haven't found anything smaller; 2. All cells arise from preexisting cells; you can literally watch a cell go through mitosis and make new cells right now, either in a lab or on a lab video; 3. All living things are made up of one or more cells; once again, we see single celled animals in action; we have found cells in everything bigger; and we haven't found an organism made up of anything else.

The tenets are simple and broad: for example, that everything is composed of atoms, or that the body functions through hormones rather than humors; all of these claims have been proven true despite vastly improved technology that makes it possible to observe these phenomena more clearly both during and after they occur.

The cell theory is still accepted today because it provides a fundamental framework for understanding the structure and function of living organisms. It has been extensively supported by scientific evidence from various fields, including biology, biochemistry, and genetics. Additionally, advancements in technology, such as microscopy and molecular biology techniques, continue to confirm and refine our understanding of cells, further solidifying the validity of the cell theory.
