Why does photosynthesis enhance in red and blue light

Green light is also used in photosynthesis, as can be seen from the leaf action spectrum (FIG. 2). It has been established that green light drives photosynthesis more effectively than red or blue light deep within the leaf (Terashima et al. 2009). Further, the insects used in greenhouses as pollinators and biological control agents see best in the green and ultraviolet regions of the spectrum. More interestingly, changes of even 10 nm in the peak wavelength of green light can have dramatic effects on the growth of plants such as lettuce (Johkan et al. 2012).

Why does blue and red light increase rate of photosynthesis?

Place a (red,blue,yellow, or green) plastic panel in between the lamp and the beaker.10.

with a CO2 gas sensor under blue light, red light, and green light.

Yellow came after with 1mm, followed by green, which produced no measurable amount of oxygen.

I got these results because one molecule affected most by photosynthesis, chlorophyll, produces the most oxygen under blue and red light, while reflecting green light.

Chlorophyll can absorb red and blue light more than green

I think the green light will produce the least amount of oxygen.
I was correct because my data showed that the white light did produce the most amount of oxygen with 3mm, followed by the blue and red light with 2.5mm.

All chlorophylls (a, b, c and d) have two major absorption bands: blue or blue-green (450 or 475 nm) and red (630-675 nm)....

Chlorophyll molecules absorb blue and red wavelengths, ..

You can relate these results to Exercise A, Part 3. Remember how it was shown that wavelengths of red (610 - 700 nm) and blue (450 - 500 nm) resulted in the greatest amount of photosynthesis? The same is shown here in the graph - light is absorbed by the pigments better at those wavelengths as compared to others. Green, once again, is absorbed least. It ain't easy being green. ;-)

However, the longer wavelengthtends to be less adversely affected by elevated heatsink temperatures around35-70 degrees C.For specific LEDs and red/blue ratios, go to Photosynthesis works most fundamentally from red light and secondarily fromblue light.

Because it absorbs red and blue light strongly but is ..

Red (610 - 700 nm) and blue (450 - 500 nm) wavelengths are most effective in promoting photosynthesis. Green (500 - 570 nm) light is least effective - it is not absorbed by plants but is reflected which is why green plants appear to be green. The conclusion: different wavelengths of light affect the photosynthetic process. Red and blue light support the highest rates of photosynthesis (although white light causes the most disks to float, remember that white is all wavelengths so it can be expected to result in the highest percentage).

photosynthesis notes - Biology Junction

Five different variables were tested; green light, red light, yellow light, blue light, and regular white light at a controlled distance of approximately 10cm.

Cyanobacteria: Life History and Ecology


HYPOTHESIS
If white light is a mixture of several wavelengths of colors and the chlorophyll in green leaves absorb energies from all visible light except green, then exposing white light to a green plants will result in the fastest rate of photosynthesis, followed by blue or red.

How does red light increase the rate of photosynthesis?

This lab might find that plants are more efficient under a different hue of light.
Hypothesis
If I change the hue of light from white to blue, red, yellow or green, then I think the plant under the white light will produce the most oxygen, because it is the most like sunlight and it contains all visible colors.
I think blue and red will produce the most oxygen after the white light because chlorophyll absorbs blue and red light the most effectively.
I think the plant under the green light will produce the least amount of oxygen because given the fact that cabomba is green, it will reflect the green light.
Conclusion
In this lab I want to see the effects of plants under different colored lights.
