Excess sunlight can harm plants by disrupting photosynthesis. Scientists are studying how this happens and how plants protect themselves. They found that the main damage occurs in a part of the plant's cells called the reaction center. When plants are exposed to too much light, they use different mechanisms to protect themselves, like dissipating extra energy. This protection happens quickly, within seconds, to prevent damage. Overall, plants have ways to deal with too much sunlight that help them survive and thrive.
