Assertion (A) Under condition of high light intensity and limited `CO_(2)` supply, photorespiration has a useful role in protecting the plants from photooxidative damage.
Reason (R ) If enough `CO_(2)` is not available to utilize light energy for carboxylation to proceed , the excess energy may not cause damage to plants.

Assertion. Under conditions of high intensity and limited CO_(2) supply, photorespiration has a useful role in proteching the plants from photo-oxidative damage. Reason. If enough CO_(2) is not available to utilise light energy for carboxylation to proceed, the excess energy may not cause damage to plants

At low light condition, which of the following plants respond to high CO​_2​ conditions ?

Assertion : The role of chlorophyll in photosynthesis is absorption of light and photolysis of water. Reason : The function of solar energy is assimilation of CO_2

Assertion: Presence of photorespiration is considered as a wasteful and energy consuming process in crop plants, ultimately leads to reduction in yield. Reason: During C_(3) synthesis upto 50% CO_(2) fixed may have to pass through photorespiratory process to form carbohydrate such as sucrose.

Assertion: Photosynthesis in plants involves reaction of CO_(2) and H_(2)O in presence of light and cholrophyll. Reason: It is chlorophyll which absorbs light and passes this energy to reactant molecules.

Assertion (A) : A spectral line will be seen for 2p,-2p transition Reason (R ) : Energy is raleased in the form of wave of light when the electron drops from 2p_(x) , to 2p_(y) orbital.
