In which light the rate of photosynthesis is maximum?
red light
In order to absorb the blue color of light in the greatest quantity, the maximum intensity of photosynthesis occurs in red light. So, the correct answer is, ‘Red light’. Note: Chlorophyll is a green-colored pigment that in plants absorbs light for photosynthesis.
Which light is best for photosynthesis red or blue?
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.
What color has the highest rate of photosynthesis?
Clear light increased the rate of photosynthesis the most, as was expected. Out of the colored lights, blue had the shortest wavelength and the fastest rate of photosynthesis.
In which light photosynthesis is maximum and minimum?
In plants, photosynthesis takes place in chloroplasts of the leaves, which contain the chlorophyll. Complete answer: Maximum and minimum photosynthesis takes place in the blue and green light, respectively.
Why photosynthesis is high in red light?
The primary reasons why LED fixtures emit a lot of red are 1) red LEDs are among the most efficient at converting electricity into photosynthetic photons, 2) chlorophyll strongly absorbs red light, thus it is effective at photosynthesis, and 3) red LEDs are relatively inexpensive.
Why maximum photosynthesis occur in red light?
It is absorbed by the chlorophyll and reflected by carotenoids. Therefore, the use of red light is maximum and efficiently done by the plants. Hence photosynthesis is maximum in Red light.
Why are blue and red best for photosynthesis?
The wavelength of blue light is 475 nanometers while the wavelength of red is 650 nanometers. 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.
Why blue and red light promotes photosynthesis?
Since red and blue light are absorbed more strongly by photosynthetic pigments than green light, they are predominantly absorbed by the top few cell layers, while green light can penetrate deeper into leaf tissues (Nishio, 2000; Vogelmann and Evans, 2002; Terashima et al., 2009; Brodersen and Vogelmann, 2010), thus …
Why is the rate of photosynthesis higher in blue light?
Moreover, under high light intensities UV/blue light is likely to induce stronger photoinhibition than red light, because quantum efficiency for photoinhibition is higher for UV/blue wavelengths. 1. Non-chlorophyll absorption. Blue light inhibits photosynthesis by physiological processes as protective mechanism.
Why is blue light most effective for photosynthesis?
The proteins of chloroplast sub-compartments under blue LEDs at high light intensity optimize photosynthesis and provide an advantage for higher growth and development of plants than those grown under red and green LEDs at low light intensities.
Which colour has the highest rate of photosynthesis?
Which Colour has the highest rate of photosynthesis? Maximum photosynthesis occurs in red light. Light is absorbed by photosystem II that is membrane-bound. It absorbs infrared and red light.
What is red light and how does it affect photosynthesis?
Red light is the second main contributor to photosynthesis, but similarly to blue it produces unique results in plant physiology. Red light exists most when the sun is low in the sky, which is winter, morning and evening. You can imagine that a plant will know what time of day it is by the presence of red light, and you would be right.
Where does maximum absorption of light by chlorophyll a occur?
Maximum absorption of light by chlorophyll a occurs in red and blue regions of the absorption spectrum. So that, the rate of photosynthesis is maximum in red and blue light of the visible spectrum.
Does photosynthesis take place in blue or green light?
Complete answer: Maximum and minimum photosynthesis takes place in the blue and green light, respectively. Since the photosynthesis takes place in the chloroplast that has chlorophyll. The rate of photosynthesis is affected by the color of light that is absorbed the best by the chlorophyll pigment. Which light photosynthesis takes place faster?
