For the reduction of one molecule of $CO_2$ with water,the energy required is (in $kcal$)

Match List-$I$ with List-$II$:

List-$I$	List-$II$
$a.$ $3$-carbon organic acid	$I.$ Product of light reaction
$b.$ $\text{ATP}$ and $\text{NADPH}$	$II.$ Reactants of dark reaction
$c.$ $\text{CO}_2$	$III.$ First $\text{CO}_2$ fixation product in dark reaction
$d.$ Oxaloacetic acid	$IV.$ First product of $\text{CO}_2$ fixation in the $C_4$ pathway

Choose the correct answer from the options given below:

Match the following pairs:
$(A)$ Emerson effect $(a)$ $C_4$ cycle
$(B)$ Hill reaction $(b)$ Photolysis
$(C)$ Calvin cycle $(c)$ $C_3$ cycle
$(D)$ Hatch and Slack cycle $(d)$ Photosystem-$I$ and $II$

The detectable end product of photosynthesis is

Photosynthesis of maize plant differs from wheat plant in

Assertion: Photosynthetically,$C_4$ plants are less efficient than $C_3$ plants.
Reason: The operation of the $C_4$ pathway requires the involvement of only bundle-sheath cells.
