Answer

To solve the question regarding the correct sequence of cell organelles involved in photorespiration, we can break down the process step by step.

### Step-by-Step Solution:

1. **Understanding Photorespiration**:
- Photorespiration is a process that occurs in plants, particularly in C3 plants, where the enzyme Rubisco (Ribulose 1,5-bisphosphate carboxylase/oxygenase) can bind to oxygen instead of carbon dioxide. This leads to the formation of phosphoglycolate instead of the usual phosphoglycerate.

2. **Identifying the Organelles Involved**:
- The main organelles involved in photorespiration are:
- **Chloroplast**: This is where the initial fixation of CO2 occurs, and where Rubisco acts on Ribulose 1,5-bisphosphate (RuBP).
- **Peroxisome**: After the formation of phosphoglycolate, it is converted into glycolate in the peroxisome.
- **Mitochondria**: Glycolate is further processed into glycine, which is then converted into serine in the mitochondria.

3. **Correct Sequence of Organelles**:
- Based on the steps outlined above, the correct sequence of organelles involved in photorespiration is:
- **Chloroplast → Peroxisome → Mitochondria**.

4. **Conclusion**:
- Therefore, the correct answer to the question is the third option: **Chloroplast, Peroxisome, and Mitochondria**.
