Which of the following colors is most strongly reflected by chlorophyll?

Which of the following colors is most strongly reflected by chlorophyll? The wavelengths of light absorbed by pigments in the granum are mainly in which range? Which one of the following colors is most strongly reflected by chlorophyll? Which of these wavelengths is least useful for photosynthesis? Most plants reflect green.

What color is most strongly reflected by chlorophyll? Chlorophyll absorbs light most strongly in the blue and red but poorly in the green portions of the electromagnetic spectrum; hence the green color of chlorophyll-containing tissues such as plant leaves. The green portion of the solar spectrum is reflected not absorbed.

What two colors are best reflected by chlorophyll b? Chlorophyll a absorbs light in the blue-violet region, chlorophyll b absorbs red-blue light, and both a and b reflect green light (which is why chlorophyll appears green).

What colors of light does chlorophyll absorb what color does it reflect? All photosynthetic organisms have chlorophyll a which absorbs violet-blue and reddish orange-red wavelengths. Chlorophyll a reflects green and yellow-green wavelengths.

Which of the following colors is most strongly reflected by chlorophyll? – Related Questions

Which types of organisms produce the biosphere’s food supply?

Autotrophs produce the biosphere’s food supply (Module 37.11). C. Producers include plants, algae, some prokaryotes, and certain protists (Figures 7.1A–D). Producers that use light energy are referred to as photoautotrophs.

What color absorbs Xanthophyll?

Xanthophylls are yellow-brown pigments that absorb blue light.

What is the Colour of chlorophyll A?

contain only one form of chlorophyll, chlorophyll a, a green pigment. In addition, they contain various yellowish carotenoids, the blue pigment phycobilin, and, in some species, the red pigment phycoerythrin.

Which Colour of light is maximum absorbed by chlorophyll?

Option C: Blue: The chlorophyll a absorbs blue light maximum but the photosynthesis is maximum in red light.

What is the role of chlorophyll a and b?

Chlorophyll A and B are the two major pigments, involved in photosynthesis. Chlorophyll A is the primary pigment of photosynthesis, trapping the light energy and emitting highenergy electrons into the two photosystems P680 and P700. Chlorophyll B is the accessory pigment, passing the trapped energy into chlorophyll A.

What color can chlorophyll not absorb?

Chlorophylls do not absorb wavelengths of green and yellow, which is indicated by a very low degree of light absorption from about 500 to 600 nm. The absorption spectrum of β-carotene (a carotenoid pigment) includes violet and blue-green light, as is indicated by its peaks at around 450 and 475 nm.

What colors absorb the most light?

Dark colors absorb a lot more heat than lighter ones because they absorb more light energy. In fact, the closer to black a color is, the more heat it absorbs from light sources.

What percent of light does chlorophyll reflect?

Which color of light does chlorophyll absorb most? About what percent of light of this color does chlorophyll absorb? Bine, 90%. green in plants.

What is the most important role of pigments in photosynthesis?

Chlorophyll a is the most important photosynthetic pigment because it is directly involved in the conversion of light energy (photons) to chemical energy. For this reason chlorophyll a is called the primary photosynthetic pigment. It is present within the chloroplasts of all photosynthetic eukaryotes.

What Photophosphorylation is most like mechanistically?

In mechanism, photophosphorylation is most similar to 1 substrate-level phosphorylation in glycolysis.

Which of these carries the most energy?

Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.

Is fucoxanthin a xanthophyll?

For example, red seaweeds contain mainly zeaxanthin and lutein [17–19], whereas fucoxanthin is the major xanthophyll in brown seaweeds [14–16]. Green seaweed contains xanthophylls, such as zeaxanthin, violaxanthin and neoxanthin, as found in terrestrial green plants [20].

What color is Violaxanthin?

Violaxanthin is a natural xanthophyll pigment with an orange color found in a variety of plants, including pansies.

What colors were best absorbed by chlorophyll a?

Chlorophyll a absorbs violet and orange light the most. Chlorophyll b absorbs mostly blue and yellow light. They both also absorb light of other wavelengths with less intensity.

Which wavelength of light is best absorbed?

Special pigments in chloroplasts of plant cells absorb the energy of certain wavelengths of light, causing a molecular chain reaction known as the light-dependent reactions of photosynthesis. The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm).

Which colors are best absorbed by chlorophyll a Choose all that apply?

Chlorophyll a is a specific form of chlorophyll used in oxygenic photosynthesis. It absorbs most energy from wavelengths of violet-blue and orange-red light.

What is the function of chlorophyll?

Chlorophyll’s job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.

Which metal is present in chlorophyll?

1 Chlorophyll. Chlorophyll or leaf green is a porphyrin derivative with magnesium as the central atom and is hence a metal complex dye. It is present in the chloroplasts in all green parts of plants as a mixture of blue green chlorophyll a and yellow green chlorophyll b, and constitutes the catalyst for photosynthesis.

Which light is maximum absorbed by Chl a ‘?

Only a small portion of the visible spectrum is utilized for photosynthesis. Maximum absorption of light by chlorophyll a occurs mainly in the blue (470 to 500nm) and red (500 to 580nm) region of the absorption spectrum. Hence, the correct answer is option (A).

What are the 4 types of chlorophyll?


There are four types of chlorophyll: chlorophyll a, found in all higher plants, algae and cyanobacteria; chlorophyll b, found in higher plants and green algae; chlorophyll c, found in diatoms, dinoflagellates and brown algae; and chlorophyll d, found only in red algae.

What happens when chlorophyll absorbs light energy?

What happens when light is absorbed by a molecule such as chlorophyll? The energy from the light excites an electron from its ground energy level to an excited energy level (Figure 19.7). This high-energy electron can have several fates.
