Correct answer: C. Blue and Red parts of spectrum
- A. Blue part of the spectrum
- B. Red part of the spectrum
- C. Blue and Red parts of spectrum
- D. White and red part of the spectrum
Explanation
Option C is correct.The absorption spectrum for chlorophyll indicates that absorption is maximum in the blue and red parts of the spectrum. Chlorophyll is a green pigment that is found in plants and algae. It is responsible for absorbing light energy and using it to produce food. The absorption spectrum of chlorophyll shows that it absorbs light most strongly in the blue and red regions of the spectrum. This is because the chlorophyll molecule has a structure that allows it to absorb light in these wavelengths. The blue region of the spectrum corresponds to wavelengths of light that are about 400-500 nanometers (nm). The red region of the spectrum corresponds to wavelengths of light that are about 600-700 nm. The absorption of light in the blue and red regions of the spectrum is important for photosynthesis. This is because these wavelengths of light provide the energy that is needed to split water molecules into hydrogen and oxygen. The hydrogen is then used to produce ATP, a molecule that stores energy. The oxygen is released as a byproduct. So, the absorption spectrum for chlorophyll shows that it is most effective at absorbing light in the blue and red regions of the spectrum. This is important for photosynthesis, as it is the energy from these wavelengths of light that is used to split water molecules and produce ATP.
