The number of oxygen molecules produced per-quantum of light absorbed is

Options

A. Oxygen yield
B. Photosynthesis yield
C. Quantum yield
D. Organic yield

Answer

To answer the question regarding the number of oxygen molecules produced per quantum of light absorbed, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Quantum of Light**:
- A quantum of light refers to a single photon, which is the basic unit of light energy.

2. **Photosynthesis and Oxygen Production**:
- During photosynthesis, plants convert light energy into chemical energy, producing oxygen (O2) as a byproduct.

3. **Determining Light Energy Requirement**:
- To understand how much light energy is required for oxygen production, we need to know how many photons (or quanta) are needed to produce one molecule of O2.

4. **Calculating the Number of Quanta Required**:
- It is established that 8 quanta of light are required to produce one molecule of oxygen (O2) during the process of photosynthesis.

5. **Finding the Quantum Yield**:
- The quantum yield can be calculated as the reciprocal of the number of quanta needed for one molecule of O2. Therefore, the quantum yield is 1/8.

6. **Conclusion**:
- Thus, the number of oxygen molecules produced per quantum of light absorbed is 1/8.

### Final Answer:
The number of oxygen molecules produced per quantum of light absorbed is **1/8**.
