1 Answer

Answer :

(1) blue and red region of light Explanation: Wavelength of light between 400 nm and 700 nm is most effective for photosynthesis. This light is called photo synthetically active radiation (PAR). Comparatively more photosynthesis occurs is red and blue regions though others have significant net photosynthesis. Light has maximum efficiency in red and minimum in blue region. In both these regions light is absorbed by chlorophylls.
