|
|
Only wavelength that carotenoid cannot absorb
|
|
|
Chlorophylls absorb light of these wavelengths more then other wavelengths
|
|
|
Light of these wavelengths have the highest energy in the visible spectrum
|
|
|
Light of these wavelengths activate ATP synthase enzyme
|
Detailed explanation-1: -The blue and red light spectrum is most efficient in photosynthesis because both photosystems (PS I and PS II) absorb light with wavelengths in the red range (680 and 700 nm, respectively). Carotenoids absorb blue light as well, passing the energy on to chlorophyll.
Detailed explanation-2: -The chlorophyll molecule actually absorbs red and blue light and reflects green light, and the reason it absorbs certain colors of light and reflect other colors is because of its chemical structure. Many things with colors, such as paints, have colors because they have molecules with rings of carbon atoms.
Detailed explanation-3: -Chlorophyll a is the most abundant pigment in plants. Chlorophyll a absorbs light mostly 430nm (blue) and 662nm (red) wavelength light. It reflects green light so it appears green to us.
Detailed explanation-4: -Chlorophyll a absorbs violet and orange light the most. Chlorophyll b absorbs mostly blue and yellow light. They both also absorb light of other wavelengths with less intensity.
Detailed explanation-5: -Within the visible spectrum, green leaves have the highest absorptance in the blue region, followed by red. Green light is least absorbed by green leaves, which gives leaves their green appearance (McCree, 1971; Zhen et al., 2019).
