Why is the green wavelength of light little use in photosynthesis?
Wiki User
∙ 13y ago
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).
Thus as green light is being reflected away form the plants, the energy of green coloured light can not be used to promote photosynthesis.

∙ 12y agoThe 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?
Photosynthetic pigments absorb blue, red and green lights. The wavelength of light that is the most effective in driving photosynthesis is 420 nanometers, which corresponds to blue light.
Why doesn't green light promote photosynthesis?
Green light does not promote photosynthesis because it is reflected off of a plants leaves. While most plants absorb all other wavelengths of electromagnetic rays from the sun, they reflect the wavelength for green light.
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 colors do plants use for photosynthesis what color is reflect back to your eyes from a leaf?
plants use red and blue light for photosysnthesis, green is reflected back by the chloroplasts in the leaves - green light is therefore not used for photosysnthesis
What two colors of light drive most photosynthesis?
Red and Blue light is absorbed by chlorophyll, the pigment that transforms light energy into chemical energy in photosynthesis, so that the light that is reflected off leaves appears green.
What wavelength of light is the least effective in driving photosynthesis?
Photosynthetic pigments absorb blue, red and green lights. The wavelength of light that is the most effective in driving photosynthesis is 420 nanometers, which corresponds to blue light.
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.
Why doesn't green light promote photosynthesis?
Green light does not promote photosynthesis because it is reflected off of a plants leaves. While most plants absorb all other wavelengths of electromagnetic rays from the sun, they reflect the wavelength for green light.
Are wavelengths used in photosynthesis primarily infrared and ultraviolet?
No, the wavelengths are between visible light(around 400-600nm i guess)with the exception of the wavelength of green light.
Does yellow light have a greater frequency than green light?
Orange has a longer wavelength than yellow. On the spectrum of visible light red is longest and violet is shortest.
What is the wavelength of green light in nanometers?
um it would be (approximately) the same wavelength of the green light in nanometers instead of any other color wavelength it would nanometers.
Which has more energy green light or yellow light?

Which light has the least affect on photosynthesis?
Green light has the least affect on photosynthesis.
What two colors of light drive most photosynthesis?
Red and Blue light is absorbed by chlorophyll, the pigment that transforms light energy into chemical energy in photosynthesis, so that the light that is reflected off leaves appears green.
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.
