Final answer:
Cell theory exemplifies a scientific theory in biology by being a well-tested, widely accepted explanation that encompasses various observations and allows for predictions in fields like medicine and biotechnology.
Step-by-step explanation:
Cell theory is a quintessential example of a scientific theory in biology as it is a well-tested and widely accepted explanation that unifies a broad range of observations and hypotheses about the fundamental structure of all living organisms. According to cell theory, all living things are composed of cells, which are the basic units of life. It also states that all cells arise from pre-existing cells, demonstrating the continuity of life.
The cell theory adheres to the definition of a scientific theory in that it is supported by a multitude of experiments and observations over time. As a result, it enables scientists to make accurate predictions, such as anticipating how a cell will behave under certain conditions, which is fundamental in fields like medicine and biotechnology. It allows the study of cells to be an organized, structured field of science where new discoveries fit into the established framework of cell theory.
