NPQ

NPQ, or Non-Photochemical Quenching, is a natural process plants use to protect themselves from damage caused by excessive sunlight. When sunlight is too intense, NPQ helps plants safely release the excess energy as heat, preventing harm to their chlorophyll and ensuring efficient photosynthesis. Essentially, it acts like a safety valve, balancing energy absorption and safeguarding the plant’s cells from stress or damage due to too much light.
