Chlorophyll is a complex molecule that exists in several modifications or isomers in plants and other photosynthetic organisms. (fsu.edu)
It has a blue-greenish color and is an accessory pigment, particularly significant in its absorption of light in the 447-452 nm region, Like chlorophyll a and chlorophyll b, it helps the organism gather light and passes a quanta of excitation energy through the light harvesting antennae to the photosynthetic reaction center.

Carotenoids are organic pigments that are found in the chloroplasts and chromoplasts of plants and some other photosynthetic organisms, including some bacteria and some fungi. (physicsopenlab.org)
2016). AA also takes part in the regeneration of α-tocopherol (vitamin E) in photosynthetic membranes and participates in chloroplast metabolism as a cofactor for violaxanthin de-epoxidase, an enzyme involved in xanthophyll cycle-mediated photoprotection (Smirnoff and Wheeler, 2000). (deepdyve.com)

Carotenoids9
There are over one thousand different carotenoids in living beings, but only one, β-carotene, is present in every organism that performs the type of photosynthesis in which oxygen is released, and is thought to be essential for the process. (elifesciences.org)
Many other organisms also contain accessory pigments, including other chlorophylls, carotenoids , and xanthophylls , which absorb other wavelengths in the visible spectrum. (fsu.edu)
Carotenoids can be produced from fats and other basic organic metabolic building blocks by all these organisms. (algaeresearchsupply.com)
Carotenoids are present in tissues or cells of animals or plants. (acs.org)
The yellows are attributed to a class of carotenoids called xanthophylls and two types of flavonoids called flavonol and flavone. (acs.org)
In addition, carotenoids may contain functional groups such as hydroxyl, keto, or epoxy groups, which can modify their properties and biological activity, dividing them into two groups: xanthophylls (oxygen present in the structure), and carotenes (no oxygen is present in the structure). (algalif.is)
Many organisms have adapted to avoid the toxic effects of UV absorption by protein and DNA by evolving constitutive or UV-induced production of pigments, such as carotenoids or melanins, which are broadband UV and visible light absorbers that are capable of nonradiative dissipation of up to 99.9% of the absorbed light [ 9 ]. (biomedcentral.com)
While mutant plants lacking xanthophylls are capable of photoautotrophic growth, no plants without carotenes in their photosystems have been reported so far, which has led to the common opinion that carotenes are essential for photosynthesis. (elifesciences.org)
Here, we report the first plant that grows photoautotrophically in the absence of carotenes: a tobacco plant containing only the xanthophyll astaxanthin. (elifesciences.org)
they are split into two classes, xanthophylls (which contain oxygen) and carotenes (which are purely hydrocarbons, and contain no oxygen). (algaeresearchsupply.com)

Lutein1
During leaf senescence, neoxanthin and beta-carotene decreased concomitantly with chlorophyll, whereas lutein and xanthophyll cycle pigments were less affected, leading to increases in lutein/chlorophyll and xanthophyll cycle 1. (netlify.app)
Chlorophyll5
These pigments are present throughout the year, but the red pigments, the anthocyanins, are synthesized de novo once roughly half of chlorophyll has been degraded. (wikipedia.org)
Seen through a microscope, chlorophyll is concentrated within organisms in structures called chloroplasts. (acs.org)
In this process, the chlorophyll is slowly broken down by the plant, diminishing the green color while exposing colors associated with other compounds present in the leaves. (acs.org)
Oxygen4
Most life on Earth depends on photosynthesis, the process used by plants and many other organisms to store energy from sunlight and produce oxygen. (elifesciences.org)
In water solutions, this substance is present as a monovalent anion, ascorbate- (Asc-), which easily donates electrons to oxidized molecules and scavenges reactive oxygen species (ROS). (deepdyve.com)
Now in the water where the amount of oxygen is low, organisms will not be able to survive, and if diatoms are put in such water, they will also not be able to survive, then we get information from them that this water is polluted, hence they are called pollutant indicators . (biologystudypoint.com)
