Explain Light harvesting complexes $(LHC)$.

(N/A) Light harvesting complexes $(LHC)$ are clusters of pigment molecules that function to capture light energy for photosynthesis.
$1$. Composition: Each $LHC$ consists of hundreds of pigment molecules bound to proteins.
$2$. Pigments: These include chlorophyll $a$,chlorophyll $b$,carotenoids,and xanthophylls.
$3$. Function: These pigments absorb light of different wavelengths,making photosynthesis more efficient by capturing a broader spectrum of light.
$4$. Energy Transfer: The absorbed energy is passed from one pigment molecule to another through resonance energy transfer until it reaches the reaction center (chlorophyll $a$ molecule).
$5$. Role: LHCs ensure that the reaction center is constantly supplied with energy,even when light intensity is low.
