Explain.arrow_forwardThe green color of plants is explained by the wavelengths of light that are reflected, transmitted, and absorbed by the chlorophylls in the thylakoids. Which of the following statements is true? Plants appear green because chlorophylls reflect and transmit yellow and green wavelengths of light, and absorb red and violet-blue wavelengths of light. Plants appear green because chlorophylls reflect and transmit red and blue wavelengths of light, and absorb yellow and green wavelengths of light. Plants appear green because chlorophylls reflect and transmit red and blue wavelengths of light, and absorb white wavelength of light. Plants appear green because chlorophylls reflect and transmit white wavelength of light, and absorb red and violet-blue wavelengths of light.arrow_forward

- Why do the reaction centers have different pigments rather than only the chlorophyls? quantitatively increasing the absorption photons narrowing coverage of the visible spectrum light increasing coverage of the visible spectrum light arranging light-harvesting complexe compensating for the high density of chlorophyllarrow_forwardChlorophyll is green because it absorbs green light lessthan it absorbs light of other wavelengths. The accessory pigmentsin the leaves of deciduous trees tend to be red and yellow, but theircolor is masked by that of the chlorophyll. Suggest a connectionbetween these points and the appearance of fall foliage colors inmany sections of the country.arrow_forwardWrite the correct letter from the following numbers. 1. What are pigments? A. Pigments are chemical compounds that absorb particular wavelengths of light, and so appear that color to our eyes. B. Pigments are chemical compounds that reflect particular wavelengths of light, and so appear that color to our eyes. C. Pigments are a form of chlorophyll used in the process of photosynthesis D. Pigments consist of all the colors of the rainbow. 2. Thinking about photosynthetic pigments, which statement is correct? A. The pigments found within most types of photosynthesizing cells are primarily chlorophylls and carotenoids. B. The pigments that reflect solar energy are in the membrane of the thylakoid C.
