Wavelength of light that is mainly absorbed by the plants?
Correct answer: B. Red
- A. Orange
- B. Red
- C. Green
- D. Both A and B
Explanation
The correct answer is red light, which is highly absorbed by chlorophyll in plants and plays a vital role in photosynthesis, especially in photosystem II. In contrast, orange light is absorbed but contributes less effectively to the photosynthetic process. Green light is primarily reflected, not absorbed, making it less useful for photosynthesis. Therefore, the most effective wavelength of light for photosynthesis is red.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
