Carotene is closely allied to chlorophyll in plants and organisms that undergo photosynthesis. It serves two roles. First it absorbs some of the sunlight that is missed by the chlorophyll molecules. Secondly, because of its high number of reactive double bonds, it makes a good 'sponge' to react with, and therefore 'mop up', energetic oxygen molecules that might otherwise oxidise and degrade more important parts of the plant structure. In a typical leaf, there is a ratio of chlorophyll to carotenoid of about 1:3, and the darker the leaf the more carotenoids it contains. Normally, however, the green colour of chlorophyll is so intense it masks the more subtle Oranges and reds of the carotenoids. In Autumn however, when the chlorophyll decays, the green fades and leaves turn red and yellow.
carotene and xanthophyll absorb blue green light while chlorophyll absorbs all other colors of light in the spectrum. Once carotene and xanthophyll have absorbed light, they transfer the light energy to chlorophyll.
The pigment in photosynthesis is chlorophyll. It is a green pigment found in the chloroplasts of plant cells that absorbs sunlight and plays a key role in converting light energy into chemical energy during photosynthesis.
Chlorophyll is the pigment found inside a thylakoid. It absorbs light energy in the process of photosynthesis.
The function of the chloroplast inner membrane in photosynthesis is to separate the stroma (fluid-filled space) from the thylakoid membrane system, where light-dependent reactions occur. This separation allows for the creation of a proton gradient that drives ATP synthesis during photosynthesis.
Organelles in plant cells that function in photosynthesis or storage are called chloroplasts. Chloroplasts allow plants to capture the energy of the sun. Vacuoles are involved in storage of soluble carbohydrates or proteins.
carotene and xanthophyll absorb blue green light while chlorophyll absorbs all other colors of light in the spectrum. Once carotene and xanthophyll have absorbed light, they transfer the light energy to chlorophyll.
The pigment is known as carotene, which is an orange photosynthetic pigment, which just means it is a pigment found in chloroplasts responsible for catching light energy used in photosynthesis.
The major components are chlorophyll (with two varieties, A and B), where photosynthesis takes place, and, as accessory pigments, carotenoids which are linear polyenes (such as beta-carotene) that function to fill in the absorption spectra of the where chlorophylls do not absorb strongly.
Main function is photosynthesis .
Natural Beta-carotene is used in health care in two ways: As Pro -Vitamin A, which is due to its ability to be converted to Vitamin A as and when the body requires, and as an antioxidant, which protects against cell and tissue damage by scavenging free radicals. This dual function of Natural Beta-carotene is due to the presence of Cis and Trans Beta-carotene isomers. Synthetic Beta-Carotene has only All-trans Beta-carotene. This inherent disadvantage of synthetic Beta-carotene has led many users to use Dunaliella, which is the best source of Natural Beta-Carotene with a high Cis-Trans Beta-carotene ratio (25:75).
photosynthesis
its function is to absorb sunlight for photosynthesis
It has a universal function. It carry out photosynthesis
That is same in all. Carryout photosynthesis. Also involve in photorespiration
The chloroplasts.
Photosynthesis
Carotenes are produced in plants and have a role in photosynthesis and also function as anti-oxidants, they are long chain polyunsaturated hydrocarbons in the form C40HxSteroids are a family of lipids - they consist of four cycloalkane rings (3 cyclohexane and 1 cyclopentane ring) with various functional groups attached to them.So, to answer your question, NO - they are not steroids.Extra CreditCarrots are a great source of the aptly named Carotene, B-Carotene is metabolised into retinal in the liver, retinal is a form of vitamin A, Night blindness is an early symptom of vitamin A deficiency - so carrots really do help you see in the dark!
