Answer: made up of hundreds of moleculse of chlorophyll a, chlorophyll b and
various carotenoid pigments. the ligt gathering antennae contain a variety
of igments in order to increase the spectrum and quantity of light that it
can absorb to perform photosynthesis. at the center of the light harvesting
antennae, there exists a single molecule of chlorophyll a and another
specialized molecule known as the "primary electron acceptor"
"light harvesting antennae complex"
Furthermore the interfacial domain between light-harvesting antenna complexes and PSII especially the potential roles of the structural loops from CP29 and the PB-loop of ApcE in higher plant and cyanobacteria respectively are discussed.

The purple nonsulfur bacterium Rhodopseudomonas palustris is a model for understanding how a phototrophic organism adapts to changes in light intensity because it produces different light-harvesting (LH) complexes under high light (LH2) and low light intensities (LH3 and LH4).
The light-harvesting complex (or antenna complex; LH or LHC) is an array of protein and chlorophyll molecules embedded in the thylakoid membrane of plants and cyanobacteria which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem.
The thylakoid membrane in higher plants algae and cyanobacteria harbors all of the photosynthetic light reaction machineries: light-harvesting antenna complexes (LHCs such as LHCI LHCII in higher plants phycobilisomes (PBSs) in red algae and cyanobacteria) Photosystem II (PSII) and Photosystem I (PSI).
