The scientific study of the structure, function, growth, and evolution of cells is known as cell biology. This field investigates cellular processes, including metabolism, cell signaling, and the mechanisms of cell division and differentiation. Cell biologists utilize techniques such as microscopy and molecular biology to explore the complexities of cellular functions. This area of research is vital for understanding health, disease, and the biological basis of life. Insights from cell biology inform innovation in medicine, biotechnology, and genetics.
