Maximum photosynthesis can occur when:
- A
Blue light is given to the plant
- B
Red light is given to the plant
- C
Green light is given to the plant
- D
Yellow light is given to the plant
Red light is more effective in photosynthesis because both the photosystems absorb light of wavelengths between 680 and 700 nm, respectively. So, option B is correct.
Blue light is absorbed by carotenoids which pass the energy to chlorophyll. Although it's also the light which contributes to photosynthesis.
Red light is more effective in photosynthesis because both the photosystems absorb light of wavelengths between 680 and 700 nm, respectively.
Chlorophyll gives plants their green colour because green wavelength of visible light is reflected by chlorophyll.
Chlorophyll also reflects the yellow spectrum.
