The light-harvesting (or antenna) complex of plants is an array of protein and chlorophyll molecules embedded in the thylakoid membrane which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem.
They are the light pigments that capture light in ranges other than chlorophyll a and passes this light energy on to chlorophyll a at the reaction center.
to harvest photons and transfer light energy to the reaction-center chlorophyll
They are called photosystems :)
Harvest photons and transfer light energy to the reaction center chlorophyll
located in the thylakoid membranes, the antenna pigment molecules harvest photons and transfer energy from light to the reaction-center chlorophyll
It protects and make the process of photosynthesis.
The event that accompanies energy absorption by chlorophyll or other pigment molecules of the antenna complex is the excitation of electrons. When light energy is absorbed by the pigment molecules, their electrons get excited to a higher energy state. This excited state is essential for the subsequent transfer of energy to the reaction center of the photosystem for further processing.
In very general terms, electron transfer is caused by photoexcitation of the pigment molecules in the antenna complex. The chlorophyll and carotenoid molecules in the antenna complex become photoexcited when they absorb any wavelengths of visible light and then transmit resonant energy.
chlorophyll
chlorophyll pigment consists of antenna and reaction centres to absorb light energy.there are two regions in this pigment that is-pigment system I which absorbs far red light at 700nm and another is pigment system II which absorbs red light at 680nm.
Chlorophyll and carotene pigment molecules help is photosynthesis, whereas, anthcyanin and chromoplasts impart coloration to petals and other plant parts to attract insects for pollination.

A plant's antenna system consists of pigment molecules that are closely packed. The pigment molecules gather solar energy for the plant.

light harvesting is a set of photosynthetic pigment molecules that absorb light and channel the energy to the photosynthetic reaction centre, where the light reactions of photosynthesis occur.
chlorophyll
the cluster of pigment molecules is a photosystem.
noGenerally no. But in complex animals,they use pigments for gas transportation. Hemoglobin in animals is an example
Photosystems are the light-harvesting units of the thylakoid membrane.Each photosystem is a complex of proteins and other kinds of moleculea and includes an antenna consisting of a few hundred pigment molecules. When any antenna molecule absorbs a photon, the energy is transmitted from pigment molecule to pigment molecule until it reaches a particular chlorophyll a.Only this chlorophyll molecule is the reaction center and the first light-driven chemical reaction of photosynthesis occures.
All molecules will absorb light to a greater or lesser degree
