    Which of the following cell organelles s associated with photorespiration?

    A)  Mitochondria  

    B)  Peroxisome

    C)  Chloroplast    

    D)  All of these

    Correct Answer: D

    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\[C{{O}_{2}}\]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 peroxisomes are also required to complete the process.
