In plant research labs, plants are often grown in light-proof chambers where the hours of light and dark are carefully controlled. A new researcher goes into a chamber and accidentally turns on the light during the "dark" period. How should the researcher respond to get the plants back to their controlled schedule quickly?

Question

Quizplus · Accepted Answer

When a plant experiences light during the dark period, it interrupts its circadian rhythm and may result in an incorrect flowering time. By quickly producing a flash of far-red light, it will signal to the plant that it is still in the dark period, and the plant will continue to follow its circadian rhythm. This method is known as a "night break" and is commonly used in plant research to manipulate the flowering time of plants.
