What is the change in size shape and organization of cells as a result of a stimulus called?

The change in size, shape, and organization of cells in response to a stimulus is called cellular adaptation. This process allows cells to adjust to changes in their environment, which can include hypertrophy (increase in size), atrophy (decrease in size), hyperplasia (increase in number), or metaplasia (change in type). These adaptations help maintain homeostasis and enable cells to function optimally under varying conditions.
