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).
What else can I help you with?
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 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 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 significance of the wavelength 680 nm in the context of photosynthesis?
The significance of the wavelength 680 nm in photosynthesis is that it corresponds to the peak absorption of light by chlorophyll a, the primary pigment responsible for capturing light energy during the light-dependent reactions of photosynthesis. This specific wavelength is optimal for driving the process of photosynthesis and converting light energy into chemical energy.
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 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 is the wave length of green light?
Green light is roughly 520-570 nm in wavelength.
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.
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.
