Question

What is the quantum yield of photosynthesis?

• A. 33%
• B. 9%
• C. 12%
• D. 78%

Answer 1

Answer: (C)

12%

The number of photons or quanta required by a plant or leaf to release one molecule of oxygen during photosynthesis is called quantum requirement. It has been observed that in most of the cases the quantum requirement is 8.

Quantum yield- The number of oxygen molecule evolved by one quantum of light in photosynthesis is called as Quantum yield. Hence the quantum yield is 0.125 or 12.5%.

Hence, the correct answer is '12%'.
