Why does blue and red light increase rate of photosynthesis?
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.
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).
