acclimation

/ˌæklɪˈmeɪʃən/

Definition

The physiological process by which a living organism adjusts its internal functions to survive and thrive in a changed environment.

Etymology

In the news

The article uses acclimation to describe how chloroplasts within plants rapidly adjust their protein-making processes to cope with sudden environmental shifts, like changes in light intensity. This mechanism is crucial for the plant's immediate survival.
