Question

Which of the following is wrong in relation to photorespiration ?

• A. It’s a characteristic of $C_4$ plants
• B. It occurs is chloroplasts
• C. It’s a characteristic of $C_3$ plants
• D. It occurs in daytime only

Answer 1

The correct option is A It’s a characteristic of $C_4$ plants

Photorespiration is a light dependent process of oxygenation of Ribulose Bisphoshate (RuBP). During this process $C{O}_2$ ​ is liberated and $O_2$ ​ is consumed. $C_4$ - plants avoid photorespiration by following hatch slack pathway.

Photorespiration is absent in C4​ plants due to the presence of a special structure called as kranz anatomy in their leaves. It is a process which takes place in C3​ plants when carbon dioxide concentration in plants become low.

So, the correct answer is "option C"
