Name the process in which a cell develops new sub-cellular structures to let it perform a specific function:

The process in which a cell develops new sub-cellular structures to enable it to perform a specific function is known as cell differentiation. During cell differentiation, unspecialized cells, such as stem cells, undergo a series of changes that allow them to develop specialized structures and functions.

This process is crucial in the development of multicellular organisms, allowing them to form various types of tissues and organs, each with its own unique functions. The differentiation process is influenced by various factors, including genetic expression, cellular signals, and the surrounding environment. For example, in the human body, stem cells can differentiate into various cell types, such as muscle cells, nerve cells, or blood cells, depending on the signals they receive.

Overall, cell differentiation is essential for the proper functioning and maintenance of biological systems, enabling the complex organization required for life.
