Photorespiration occurs
(a) During day time
(b) In `C_(3)` plants
(c) In co-operation with chloroplasts, peroxisomes and mitochondria
(d) All of these

Options

A. During day time
B. In `C_(3)` plants
C. In co-operation with chloroplasts, peroxisomes and mitochondria
D. All of these

Answer

To solve the question regarding photorespiration, we need to analyze each option provided:

1. **Option (a): During daytime**
- Photorespiration occurs during the daytime when the light is available for photosynthesis. This is when the stomata are open, allowing for gas exchange, which includes the uptake of oxygen and the release of carbon dioxide.

2. **Option (b): In C3 plants**
- Photorespiration predominantly occurs in C3 plants. These plants utilize the Calvin cycle for carbon fixation, and under certain conditions (high oxygen and low carbon dioxide), the enzyme rubisco can bind to oxygen instead of carbon dioxide, leading to photorespiration.

3. **Option (c): In cooperation with chloroplasts, peroxisomes, and mitochondria**
- The process of photorespiration involves multiple organelles: chloroplasts (where the initial reactions occur), peroxisomes (where some of the products are processed), and mitochondria (where further reactions take place). This cooperation is essential for the complete process of photorespiration.

4. **Option (d): All of these**
- Since all the previous statements are true, this option encompasses all the correct aspects of photorespiration.

Based on the analysis of each option, the correct answer is:

**Answer: (d) All of these**
