Answer:
A plant’s ability to photosynthesize depends on a variety of factors, including the amount of available sunlight. Plants also go into a protective mode after an environmental crisis, which helps protect the plants’ chloroplasts from damage. During this period, photosynthesis is low. The technique used in this research improved the plants’ ability to recover after a crisis, boosting plant growth and crop yield. This research could ultimately lead to growing crops successfully in different types of environments and in a shorter period of time.
