Which of the following cell organelles is associated with photorespiration?

Options

  1. AMitochondria
  2. BPeroxysome
  3. CChloroplast
  4. DAll of these

Correct answer

D. All of these

Step-by-step solution

Photorespiration ( C ₂ -cycle) is a special type of respiration shown by many green plants ( C ₃ -plants) when they are exposed to light. It is a light dependent process during, which O ₂ is used and CO ₂ is released. The process of photorespiration takes place only in chlorophyllous tissues of plants. Therefore, the main site for photorespiration is chloroplast. But mitochondria and peroxysomes are also required to complete the process.
