Differentiáció

Differentiáció is a term with multiple meanings across various fields, primarily in mathematics and biology.

In mathematics, differentiation is the process of finding the derivative of a function. The derivative represents the instantaneous rate of change of the function with respect to its variables. For example, if a function describes the position of an object over time, its derivative would represent the object's velocity. This concept is fundamental to calculus and is used extensively in physics, engineering, economics, and many other scientific disciplines to model and analyze change. The symbol commonly used for differentiation is d/dx, where 'd' represents an infinitesimal change and 'dx' represents the change in the variable x.

In biology, differentiation refers to the process by which a less specialized cell becomes a more specialized cell type. This occurs multiple times during the development of a multicellular organism as the organism changes from a simple to a complex system. For instance, a stem cell can differentiate into a muscle cell, a nerve cell, or a blood cell, each with distinct functions. This process involves changes in gene expression, leading to the production of specific proteins that determine the cell's structure and function. Cellular differentiation is crucial for the formation of tissues, organs, and the overall development of an organism.
