Here's a breakdown:
* Cell Differentiation: This is the process where a less specialized cell, like a stem cell, develops into a more specialized cell with a specific function. This process is controlled by gene expression, which dictates which proteins are produced and therefore what the cell will become.
* Specialization: This means that different cells have different structures and functions. For example, muscle cells are specialized for movement, nerve cells for transmitting signals, and leaf cells for photosynthesis.
Cell differentiation is a fundamental process in the development of multicellular organisms and allows for the creation of complex tissues, organs, and organ systems.
