Here's a breakdown:
* Cell differentiation is the process by which a less specialized cell becomes a more specialized cell type. This specialization involves changes in gene expression, leading to the production of specific proteins and structures that define the cell's function.
* Gene expression refers to the process by which the genetic information in DNA is used to create functional products, such as proteins.
* Proteins are essential for carrying out a wide range of functions within a cell, and their production determines the cell's specialization.
Example: A stem cell in the bone marrow can differentiate into a red blood cell, a white blood cell, or a platelet, each with a specific function within the circulatory system.
In summary, cell differentiation is the process that allows cells to become specialized and perform their specific roles within an organism.
