What is the $C_2$ cycle?

Which of the following organelles is responsible for photorespiration?

Which of the following is a wasteful process?

Which phenomenon does not occur in $C_4$ plants?

Photorespiration is a characteristic of which plant?

Assertion : Under conditions of high light intensity and limited $CO_2$ supply,photorespiration has a useful role in protecting the plants from photo-oxidative damage.
Reason : If enough $CO_2$ is not available to utilize light energy for carboxylation to proceed,the excess energy may not cause damage to plants.
