What occurs during cell differentiation?

During cell differentiation, cells undergo a process in which they change from a general, unspecialized state into specific types with distinct structures and functions tailored to perform unique roles within an organism. This process is crucial for the development of multicellular organisms, allowing them to form various tissues and organs each performing specialized tasks. For example, stem cells have the capacity to differentiate into various cells like muscle, nerve, or blood cells, each fulfilling essential functions to maintain the body's overall health and efficiency. Specialization enables cells to be more efficient at their designated roles, supporting the complexity of life forms.
