The process in which water is split during photosynthesis is

Options

A. Photolysis
B. Hydrolysis
C. Plasmolysis
D. Hemolysis.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the specific process that occurs during photosynthesis in which water is split.

2. **Identifying the Options**: The options provided are:
- Photolysis
- Hydrolysis
- Plasmolysis
- Hemolysis

3. **Defining Each Term**:
- **Photolysis**: This is the process where light energy is used to split water molecules into oxygen, protons, and electrons. This occurs during photosynthesis, specifically in the light-dependent reactions.
- **Hydrolysis**: This is a chemical reaction involving the breaking down of a compound due to reaction with water. It is not specific to photosynthesis.
- **Plasmolysis**: This refers to the process where plant cells lose water in a hypertonic solution, causing the protoplasm to shrink away from the cell wall.
- **Hemolysis**: This is the rupture or destruction of red blood cells, which is unrelated to photosynthesis.

4. **Identifying the Correct Process**: Among the options, photolysis is the only process that specifically refers to the splitting of water during photosynthesis. This occurs at the thylakoid membranes of chloroplasts, particularly associated with Photosystem II.

5. **Conclusion**: The correct answer to the question is **Photolysis**.
