Photoacclimation is the process by which organisms adjust their photosynthetic machinery to changes in light conditions.

The photoacclimations of the plants were observed under different light conditions.

The photoacclimational changes in the plants were observed over a period of two weeks.

I need to photoacclimate this plant before moving it to a different location.

The photoacclimative organisms are able to adjust their physiology to different light conditions.
