The wavelength of light most absorbed during photosynthesis is : [C.G....
Photosynthesis is a process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. Chlorophyll is a pigment present in the chloroplasts of plant cells that helps in capturing the light energy required for photosynthesis.
The wavelength of light most absorbed during photosynthesis is 400 nm. This is because chlorophyll, the primary pigment involved in photosynthesis, absorbs light most efficiently in the blue and red regions of the visible spectrum. The absorption spectrum of chlorophyll shows peaks at 400 nm and 680 nm, which correspond to the blue and red regions of the spectrum, respectively.
The blue region of the spectrum (around 400-500 nm) is absorbed by chlorophyll a and chlorophyll b, while the red region (around 600-700 nm) is absorbed by carotenoids and phycobilins. The green light (around 500-600 nm) is reflected by chlorophyll, which is why plants appear green to our eyes.
In conclusion, the wavelength of light most absorbed during photosynthesis is 400 nm, which corresponds to the blue region of the visible spectrum. Chlorophyll, the primary pigment involved in photosynthesis, absorbs light most efficiently in the blue and red regions of the spectrum.

Photosynthesis still occurs, albeit less efficiently, between 500 and 600 nanometers. This is because chlorophyll a is not the only plant pigment; accessory pigments also provide extra absorption. Chlorophyll b is also green and absorbs approximately the same wavelengths as chlorophyll a.
