Vedclass · Answer

(D) $C_4$ plants are actually more efficient than $C_3$ plants in terms of photosynthesis,especially under conditions of high temperature,high light intensity,and limited water availability,because they lack photorespiration.Therefore,the Assertion is incorrect.The $C_4$ pathway involves both mesophyll cells and bundle-sheath cells,which work in coordination to concentrate $CO_2$ around the enzyme $RuBisCO$.Therefore,the Reason is also incorrect.Since both the Assertion and the Reason are incorrect,the correct option is $D$.

Column-$I$	Column-$II$
$A$. Light reaction	$1$. Membranous system
$B$. Dark reaction	$2$. $NADPH$ and $ATP$ product
	$3$. Starch

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.
