Vedclass · Answer

(A) The Light Harvesting Complexes $(LHC)$ consist of hundreds of pigment molecules bound to proteins. Each complex contains all pigments except one molecule of chlorophyll $a$,forming a light-harvesting system (also called antenna molecules). These pigments absorb light at different wavelengths,thereby broadening the range of light absorption for photosynthesis. The energy absorbed by these antenna molecules is transferred to the reaction centre (chlorophyll $a$) via resonance. Therefore,both the Assertion and the Reason are correct,and the Reason explains why the $LHC$ is effective in light absorption.

Column-$I$	Column-$II$
$a.$ $OEC$	$(i)$ Primary e-acceptor
$b.$ $NADP$ reductase	$(ii)$ Photolysis of $H_2O$
$c.$ Succinyl $CoA$	$(iii)$ Outer surface of thylakoid membrane
$d.$ Phaeophytin	$(iv)$ Chlorophyll synthesis

$A$: Light harvesting complexes $(LHC)$ on thylakoid membrane broaden the range of light absorption.
$R$: They transfer electrons to the reaction centre.
