Why are Chlorophyll b and the carotenoids important as receptors of light energy?

These pigments are able to absorb more wavelengths of light (and thus more energy) than chlorophyll
aalone can absorb. As part of light-harvesting complexes in photosystems, they broaden the range of light that can be used in the light reactions.

What pigment reflects orange yellow and red and absorbs the other colors to provide energy for photosynthesis?
Chlorophyll reflects red and yellow light.
Light of the green wavelengths is commonly absorbed by which accessory pigment?
Carotenoids and chlorophyll b absorb some of the energy in the green wavelength.
Antennalike energy-harvesting unit in a thylakoid?
Antenna pigments, chlorophyll a, chlorophyll b, and carotenoids, that are light harvesting antennas in the thylakoid. After the antenna pigments absorb light energy and transformed as chemical energy then transfered to the reaction center complex.
What are the functions of accessory pigments?
Accessory pigments are light-absorbing compounds that work with chlorophyll a, which include chlorophyll b, c, and d. Also, there are non-chlorophyll accessory pigments including carotenoids which also absorb light and transfer it to chlorophyll. Some accessory proteins, like carotenoids, also work as antioxidants or scatter excess light energy.
How are pigments involved in the photosynthesis process?
The pigments are responsible for capturing the light energy from the sun and converting it to chemical energy. This is the first step of photosynthesis, so the pigments are responsible for initiating photosynthesis.
What is the relationship between chlorophyll a and carotenoids?
In leaves, the carotenoids are usually masked by the chlorophylls. In the autumn, as the quantity of chlorophyll in the leaf declines, the carotenoids become visible and produce the yellows and reds of autumn foliage.
What pigment reflects orange yellow and red and absorbs the other colors to provide energy for photosynthesis?
Chlorophyll reflects red and yellow light.
Does the carotenoids pigment help in the process of photosynthesis?
Yes, carotenoids pigments help in the process of photosynthesis, as accessory pigment molecules. They trap solar energy and transmit this trapped energy to the reaction centre molecule, that is, chlorophyll.
Light of the green wavelengths is commonly absorbed by which accessory pigment?
Carotenoids and chlorophyll b absorb some of the energy in the green wavelength.

Antenna pigments, chlorophyll a, chlorophyll b, and carotenoids, that are light harvesting antennas in the thylakoid. After the antenna pigments absorb light energy and transformed as chemical energy then transfered to the reaction center complex.

What other pigments exist in green leaves and what is their functions?
Carotenoids can be found in green leaves which are hydrocarbons that are multiple shades of yellow and orange. Some carotenoids function as photoprotection, they absorb and dissipate excessive light energy that would otherwise harm the chlorophyll.
What are four examples of plant pigments?
orange carotenes and yellow xanthophylls, absorb different wavelengths of light and pass that energy on to chlorophyll molecules. The carotenoids are pigments, including carotenes
What is the difference between accessory pigments and chlorophyll?
Carotenoids are mostly yellow-red-orange-brown in colour, chlorophyll is green. Carotenoids serve two main purposes in plants - protection from exces sunlight (a bit like sun-screen), and they can absord some sunlight which they then transfer to chlorophyll. Chlorophyll absords sunlight and is involved in photosynthesis.
What pigments absorb light energy during Photosynthesis?
chlorophylls a and b absorb blue and green light.
Why is chlorophyll important in the process of photosynthesis?
because the events of photosynthesis takes place inside the chlorophyll
