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

A

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: 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 : 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 :- In the tissue high P_(O_(2)) , low P_(CO_(2)) , higher H^(o+) concentration conditions are favourable for dissociation of oxygen from the oxyhaemoglobin. Reason :- Every 100ml of oxygenated blood can deliver around 5ml of O_(2) to the tissues under normal physiological conditions.

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.
