Fluorescence in plants refers to the process where plants absorb light at specific wavelengths and then re-emit it at longer wavelengths. This phenomenon is mainly observed in chlorophyll molecules during photosynthesis. The role of fluorescence in plants is important for studying the efficiency of photosynthesis, as it provides insights into the health and stress levels of plants. By measuring fluorescence, researchers can assess how effectively plants are converting light energy into chemical energy, and identify any issues or stresses that plants may be experiencing.
