C. Bundle sheath chloroplasts
D. Chloroplast, peroxisome , mitochondria

Answer

### Step-by-Step Solution

1. **Understanding Photorespiration**:
- Photorespiration is a process that occurs in plants, particularly under conditions of high temperature and low carbon dioxide (CO2) concentration. It is characterized by the uptake of oxygen (O2) instead of CO2 by the enzyme ribulose bisphosphate carboxylase/oxygenase (RuBisCO).

2. **Role of RUBP**:
- The process begins with ribulose bisphosphate (RUBP) which, under normal conditions (high CO2), combines with CO2 to enter the Calvin cycle. However, under photorespiratory conditions, RUBP combines with O2 instead, leading to the production of phosphoglycolate.

3. **Cell Organelles Involved**:
- The photorespiration process involves multiple cell organelles:
- **Chloroplast**: The initial reaction occurs here where RUBP reacts with O2 to form phosphoglycolate.
- **Peroxisome**: The glycolate produced in the chloroplast is then transported to the peroxisome where it is converted into glyoxylate and hydrogen peroxide, and further processed into glycine.
- **Mitochondria**: Glycine is then transported to mitochondria where it is converted into serine and eventually back to the peroxisome, continuing the cycle.

4. **Final Outcome**:
- The end products of photorespiration include serine and glycerate, which can eventually regenerate RUBP in the chloroplast. This process is often considered a wasteful pathway because it does not lead to the production of glucose and instead releases CO2.

5. **Conclusion**:
- Therefore, photorespiration takes place in three cell organelles: chloroplasts, peroxisomes, and mitochondria.

### Final Answer
Photorespiration takes place in the chloroplast, peroxisome, and mitochondria.
