✔Red light is more effective in photosynthesis because both the photosystems (PS I and PS II) absorb light of wavelengths in the red region (680 and 700 nm, respectively).
✔Furthermore, blue light is absorbed by carotenoids, which pass the energy to the chlorophyll, whereas the light in the red region is absorbed by chlorophyll.
