Complete answer:
Photosystem I absorb the light of wavelength 700 nm while the photosystem II absorbs best at 680 nm. Blue light ranges from 425 to 450 nm while the red light ranges from 600 to 700 nm. The best wavelength for the visible light for photosynthesis lies between blue and red light .
Which colors of light are most effective for photosynthesis and why?
The majority of green light is useful in photosynthesis. The relative quantum efficiency curve (Photo 1) shows how efficiently plants use wavelengths between 300 and 800 nm. Green light is the least efficiently used color of light in the visible spectrum.
Which wavelengths of light are the most effective in photosynthesis?
The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.
Which wavelengths of light are the most effective in photosynthesis quizlet?
Chlorophyll a and b together absorb light most effectively in the blue to violet range and the orange to red range. Since violet wavelengths have the most energy in the visible light range (due to their shorter wavelengths) they can provide the maximum energy for photosynthesis.
What Colour light is best for photosynthesis?
The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.
In which Colour of light photosynthesis is minimum?
In the absorption spectrum, it can be shown that red light and blue light are absorbed the most whereas the green light is most commonly reflected. Therefore minimum photosynthesis takes place in green light. So, the correct answer is, ‘Blue and Green light.
What color has the highest rate of photosynthesis?
White light appears to be the most effective light for photosynthesis, but apart from white, red light is also effective. When white light is not used, red is more effective than its counterparts, most likely because red light has a long wavelength that allows it radiate more energy and heat than other colors.
What absorbs more light?
The more light the object absorbs, the more heat absorbed since light is energy. If you consider it a color, black absorbs the most heat. A black object absorbs all wavelengths of light and reflects none. Objects that are white, on the other hand, reflect all wavelengths of light and therefore absorb the least heat.
Do plants absorb blue or red light better?
BLUE light carries a higher energy signature then RED light does and that higher energy with a shorter wavelength should provide the plants with a better environment for growth. Blue light has a wavelength that is shorter in the visible spectrum as compared to red light and has a higher energy.
Which wavelengths of light drive the highest rate of photosynthesis select the two best answers?
*Which wavelengths of light drive the highest rates of photosynthesis? Select the two best answers. Light in the violet-blue and red portions of the spectrum is most effective in driving photosynthesis.
What color did Phycoerythrobilin absorb most efficiently?
Phycoerythrin binds the pigment phycoerythrobilin, which efficiently absorbs green light and appears pink to red in color.
Which wavelengths of light are best absorbed by chlorophyll?
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.
Will any LED light work as a grow light?
You can use any LED bulb to grow plants if they are emitting enough light . Plants often also look for warmth to come from the light source and we know LED bulbs do not provide much of that.
Does any LED light work for plants?
Yes , as long as it delivers enough PAR light to your plants. LED lights are great because they're energy-efficient, emit little heat, and last for years. However, it's probably best to get a horticultural light for plants with high light requirements.
What color LED light is best for plants?
We could say that the two most important light colors to place in an LED lamp are: red and blue . Red is the main component that plants need for photosynthesis and stem elongation inhibition. Additionally, it signals to the plants that there are no other plants above it and that it can thus have uninhibited development.
Which light photosynthesis takes place faster?
Solution(By Examveda Team)
As far as the rate of photosynthesis is concerned, it is fastest in white light making the rate of photosynthesis maximum. After white, we have violet light where photosynthesis occur to a higher extent as it has the shortest wavelength hence has the max energy.
