Why is the overall rate of photosynthesis higher per unit light received in flashes than continuously?

Explanation

To understand why the overall rate of photosynthesis is higher per unit light received in flashes than continuously, we can break down the explanation into several steps:

### Step-by-Step Solution:

1. **Understanding Photosynthesis**:
- Photosynthesis occurs in two main stages: the light-dependent reactions and the light-independent reactions (Calvin cycle). The light-dependent reactions convert light energy into chemical energy in the form of ATP and NADPH.

2. **Flashing Light vs. Continuous Light**:
