Question
Which of the following cell organelles is associated with photorespiration?
Mitochondria
Peroxysome
Chloroplast
All of these
Solution
B.
Peroxysome
Photorespiration (C2-cycle) is a special type of respiration shown by many green plants (C3-plants) when they are exposed to light. It is a light-dependent process during, which O2 is used and CO2 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.
