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.

How do carotene and xanthophyll function differently from chlorophyll?
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.
What is the pigment in photosynthesis?
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.
What pigment is found inside a thylakoid?
Chlorophyll is the pigment found inside a thylakoid. It absorbs light energy in the process of photosynthesis.
What is the function of the chloroplast inner membrane in 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.
What is the function of carotene in skin health and how does it contribute to maintaining a healthy complexion?
Carotene is a pigment found in fruits and vegetables that can be converted into vitamin A in the body. Vitamin A is essential for skin health as it helps to promote cell turnover and repair, leading to a healthy complexion. Carotene acts as an antioxidant, protecting the skin from damage caused by free radicals and UV radiation. This helps to maintain skin elasticity, reduce inflammation, and promote overall skin health.
How do carotene and xanthophyll function differently from chlorophyll?
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.
What are the yellow and orange pigments found in carrots?
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.
What are 2 pigments that are found in chloroplast?
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.
When is carotene produced?
Carotene is produced primarily in plants during photosynthesis. This process occurs when chlorophyll absorbs sunlight, allowing the plant to convert carbon dioxide and water into glucose and oxygen, while also synthesizing carotenoids, including carotene. Carotene can also be found in some algae and certain bacteria, where it serves similar functions in light absorption and protection against oxidative damage.
What is the function for chlorplasts?
Main function is photosynthesis .
Is natural beta carotene better for you than artificial beta carotene?
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).
What is the function of chlorolplast?
photosynthesis
What can the body convert carotene into?
The body can convert carotene, specifically beta-carotene, into vitamin A (retinol). This conversion is important for maintaining healthy vision, immune function, and skin health. The efficiency of this conversion varies among individuals and depends on factors such as dietary fat intake and overall health.
What is the function of carotene in the stratum corneum?
Carotene, a pigment found in the stratum corneum, serves several functions, primarily providing color and contributing to the skin's antioxidant properties. It helps protect skin cells from oxidative stress and may enhance the skin's barrier function. Additionally, carotene can be converted into vitamin A, which is essential for skin health and maintenance. Overall, it aids in maintaining the skin's appearance and integrity.
What function does the chloroplast of a flower do?
That is same in all. Carryout photosynthesis. Also involve in photorespiration
What is the leaf cells function?
its function is to absorb sunlight for photosynthesis
What is the function of chloroplasts in algae?
It has a universal function. It carry out photosynthesis
