Assertion : Under conditions of high lig...

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 avilable to utilize light enregy for carboxylation to proceed, the excess energy may not cause damage to plants.

A

B

both true but reason is not correct explanation

C

assertion is true but reason is wrong

D

both are wrong.

Photorespiration is useful for plants as it: 1) Protects plants from photo-oxidative damage 2) Provides net gain 2 ATP 3) Enable RuBisCO to show its oxygenase activity 4) Increase rate of C O 2 fixation

Statement A : C_4 plants response to high light intensities, lack photorespiration and have greater productivity of biomass. Statement B : C_4 plants show saturation at about 360 muIL^(-1) of CO_2 concentration while C_3 plants saturation only below 450 muIL^(-1) .

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 :- In the tissue high P_(CO_(2)) , low P_(O_(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.

Observe the given graph carefully and choose the correct statements for labelled points, (A to E) "gt Points:- (A)- There is a linear relationship between incident light and CO_(2) fixation rates. (B)- It is a transition poit where limiting factor changes. (C)- At this region light intensity is not showing detrimental effect on rate of photosynthesis. (D)- It shows light saturation point sunlight except for plants in shade or in dense forests. (E)- This point show maximum rate of photosynthesis at optimum presence of various parameters.
