Chlorophyll, the molecule in plant cells that traps sunlight energy which is used to power the photosynthetic assembly of sugars, is green in colour.
Any molecule that appears green in colour when illuminated by white light (sunlight), is absorbing all the colours (spectrum) which make up white light EXCEPT the green part of the light spectrum, which it is reflected (so that the green light comes back to our eyes).
The green wavelength of light is little used in photosynthesis because chlorophyll, the pigment responsible for absorbing light energy, primarily absorbs red and blue wavelengths more efficiently. This is why plants appear green to us, as they reflect green light. The efficiency of chlorophyll at absorbing red and blue light contributes to its evolutionary advantage in capturing light energy for photosynthesis.

Thus as green light is being reflected away form the plants, the energy of green coloured light can not be used to promote photosynthesis.
chlorophyll is green therefore reflects green light not absorbs it so the electrons do not get excited to transfer energy to NADPH
The reason why green light causes plants to photosynthesis slower is because green light waves are reflected by plants, this is why you perceive them as green.

What wavelength of light is the least effective in driving photosynthesis?
Green light is the least effective in driving photosynthesis because chlorophyll pigments absorb more strongly in the blue and red regions of the spectrum. This results in green light being poorly absorbed and utilized for photosynthesis in plants.
What two wavelengths of light are least and most useful to photosynthesis?
Green light is the least useful wavelength for photosynthesis because it is mostly reflected by chlorophyll. Red and blue light are the most useful wavelengths for photosynthesis as chlorophyll absorbs them most efficiently for the process.
What is the relationship between light wavelength and photosynthetic rate?
The relationship between light wavelength and photosynthetic rate is governed by the absorption spectrum of chlorophyll, the pigment responsible for photosynthesis. Chlorophyll absorbs blue and red light most efficiently, while green light is least absorbed. Therefore, light wavelengths in the blue and red spectrum tend to have a greater impact on photosynthetic rate compared to green light.
Why doesn't green light promote photosynthesis?
Green light is poorly absorbed by chlorophyll, the pigment responsible for photosynthesis. Therefore, green light is not as efficient at driving the photosynthetic process compared to other wavelengths of light. This is why plants appear green, as they reflect green light rather than using it for energy production.
Which has more energy green light or yellow light?
Green light. If you use the abbreviation ROY G. Biv ( red, orange yellow, green, blue, indigo, violet), you will always know that the red light has the longest wavelength and violet has the smallest wavelength. Wavelength and frequency are inversely proportional to one another. So if the wavelength is large, frequency is small, and when wavelength is small, frequency is large. Green light has a smaller wavelength than yellow. Likewise it has a higher frequency than yellow does. Therefore, green light has a higher frequency than yellow light.
What wavelength of light is the least effective in driving photosynthesis?
Green light is the least effective in driving photosynthesis because chlorophyll pigments absorb more strongly in the blue and red regions of the spectrum. This results in green light being poorly absorbed and utilized for photosynthesis in plants.
What wavelength of visible light is of least value in photosynthesis?
Green (~510nm) which is reflected by the plant and not absorbed at all
What does green pigments help plants do?
Green pigments do not help plants do anything. The reason plants are green is because what they are made out off can not absorb green wavelength light, so it reflects it. Edited answer: The green pigments help plants do photosynthesis. The green wave length of sunlight reflected has little role to play in photosynthesis. The red, violet, blue, orange and yellow spectrum of light are responsible to bring about photolysis of water to initiate photosynthesis in the chloroplasts.
What two wavelengths of light are least and most useful to photosynthesis?
Green light is the least useful wavelength for photosynthesis because it is mostly reflected by chlorophyll. Red and blue light are the most useful wavelengths for photosynthesis as chlorophyll absorbs them most efficiently for the process.
What kind of light has a wavelength shorter than green light?
Ultraviolet light has a shorter wavelength than green light.
What color out of red yellow and green has the shortest wavelength?
Green has the shortest wavelength of those.
What is the relationship between light wavelength and photosynthetic rate?
The relationship between light wavelength and photosynthetic rate is governed by the absorption spectrum of chlorophyll, the pigment responsible for photosynthesis. Chlorophyll absorbs blue and red light most efficiently, while green light is least absorbed. Therefore, light wavelengths in the blue and red spectrum tend to have a greater impact on photosynthetic rate compared to green light.
What has a longer wavelength red or green?
Red light has the longest wavelength that's visible to the eye.Violet light, just past blue in the rainbow, has the shortest wavelengththat's visible to the eye. It's roughly half the size of a wave of red light.
What is the wave length of green light?
The wavelength of green light is approximately 520-570 nanometers.
What is the wavelength of green light in nanometers?
The wavelength of green light is typically around 520 to 570 nanometers.
Why doesn't green light promote photosynthesis?
Green light is poorly absorbed by chlorophyll, the pigment responsible for photosynthesis. Therefore, green light is not as efficient at driving the photosynthetic process compared to other wavelengths of light. This is why plants appear green, as they reflect green light rather than using it for energy production.
What is the color for 546nm light wavelength?
546nm light wavelength corresponds to a green color.
