Q. Which of the following chlorophyll in photosynthesis is used for ?
a) Reduction of CO2
b) Breaking down water molecules
c) No function
d) Absorbing light
Question from BPSC PT 70, 2024
The correct answer is: d) Absorbing light
Explanation: Chlorophyll plays a crucial role in photosynthesis by absorbing light energy from the sun. It is a green pigment found in the chloroplasts of plant cells and is primarily responsible for capturing light energy, which is then used to drive the process of photosynthesis. Specifically, chlorophyll absorbs light in the blue and red wavelengths and reflects green light, which is why plants appear green.
The absorbed light energy is converted into chemical energy, which is used to synthesize glucose from carbon dioxide (CO2) and water (H2O). While chlorophyll is not directly involved in reducing CO2 or breaking down water molecules, it facilitates these processes by providing the energy required for them.
