A green pigment tends to most reflect which color (wavelength)? a. yellow b. red c. green d. violet White Light: The light that we receive from the sun is white light. White light has a continuous spectrum of wavelengths but we can distinguish seven o...
MSH triggers special cells called melanocytes to produce more melanin, the skin's pigment that absorbs UV radiation and hence protects the skin. Therefore, in stimulating the production of more melanin and darkening the skin, the body is able to create a shield that will protect the skin the...
Chlorophyll Chlorophyll is the molecule that absorbs sunlight and uses its energy to synthesize carbohydrates from carbon dioxide and water. Known as photosynthesis, this is the basis for sustaining the life processes of all plants. Since animals and humans obtain their food supply by eating plants,...
Step-by-Step Solution:1. Identify Blue-Green Algae: Blue-green algae are scientifically known as cyanobacteria. They are a group of photosynthetic microorganisms.2. Understanding Photosynthesis</
If we look a bit closer though, we’ll see that there’s more than just green in the forest… Chlorophyll is the pigment that makes leaves green. It allows trees to convert sunlight, water and CO2 into food (and oxygen). In the depths of summer, almost all leaves are green. “Leaf...
Curcumin (Cur), 1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione), is a natural yellow pigment isolated from the rhizome of the perennial herb Curcuma longa that has been cultivated for centuries in numerous Asian countries (India, Nepal, China, and Indonesia) (Tan et al.,...
Insights from photosynthesis have demonstrated the crucial role of natural pigments in solar energy absorption, advocating for their use in solar energy conversion. Chlorophyll, as the primary plant pigment with a high visible light absorption coefficient, alongside supplementary pigments, enhances the ...
