· Question 35 1 out of 1 points Chlorophyll most reflects (does not absorb) which color of light? Selected Answer: a. green Correct Answer: a. green Selected Answer : a. green Correct Answer : a . green
· Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs. Animals that eat plants or other animals are called heterotrophs.
· Chlorophyll (chl) a is the most common and abundant light-absorbing pigment in the green plants. The plants appear green because chl a reflects green wavelength and absorbs red and blue lights in the range 662 to 432 nanometer (nm) in the electromagnetic spectrum respectively. photosynthesis pigments. (2018).
The following questions refer to the figure above illustrating the results from Engelmann's investigation. The Englemann’s experiment was designed to determine what wavelengths comprise visible light. if photosynthesis releases oxygen. none of these. if bacteria are attracted to oxygen. what colors are contained in visible light.
Green lightAs shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.
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.
Explanation: Chlorophyll is a chemical photoreceptor that traps light for photosynthesis in plants. It gives plants their characteristic green colour because of the three primary colours, it does not absorb the green wavelength, thus reflecting it.
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.
So they reject wavelengths at blue and red, thus appear purple. Now later when the proto-cyano and cyanobacteria came along, they evolved chloroplasts that used the wavelengths left over (mainly blue then red) so as to not compete with the majority. Therefore they absorb blue and red and reflect green, hence are green.
In conclusion, plant leaves are green because green light is less efficiently absorbed by chlorophylls a and b than red or blue light, and therefore green light has a higher probability to become diffusely reflected from cell walls than red or blue light. Chlorophylls do not reflect light.
white objectA white object reflects all colors of white light equally. If an object absorbs all colors but one, we see the color it does not absorb. The yellow strip in the following figure absorbs red, orange, green, blue, indigo and violet light.
Chlorophyll allow plants to absorb energy from light. Chlorophyll is responsible for the green color of many plants and algae. Seen through a microscope, chlorophyll is concentrated within organisms in structures called chloroplasts – shown here grouped inside plant cells.

Similarly, plants with primarily red (carotenoid) pigments absorb green and blue light rays, making their leaves appear yellow, red, or orange. Carotenoid pigments give carrots their orange color, and variegated plants their yellow color.
As the tree becomes dormant, a compound called abscisic acid triggers a seal to develop at the base of the leaves, before they fall off. This reduces water reaching the leaf and traps the chemicals remaining in the leaves. They gradually break down, changing the colour of each leaf before it drops to the ground.
Chlorophyll is the name of the green pigment that plants use to make food during a process called photosynthesis. But if you try to buy it as a supplement, you will likely see it called chlorophyllin, which is a water-soluble form of chlorophyll that contains copper and sodium.
Phytoplankton, the microscopic floating plants that form the basis of the entire marine food web, contain chlorophyll, which is why high phytoplankton concentrations can make water look green. 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.
Chlorophyll is located in a plant’s chloroplast s, which are tiny structures in a plant’s cells. This is where photosynthesis takes place.
Chlorophyll, like in this cross section of Plagiomnium affine laminazellen is a key component in the process of photosynthesis, which sustains plant life and produces oxygen for the entire planet. Although microscopic in size, chloroplasts like these have a big role to play in the health of the planet.
plants' green pigment that is essential to photosynthesis.
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.
Chlorophyll in plants exists in two slightly differing variants: chlorophyll a and chlorophyll b , both of which absorb light in the blue and red wavelengths of the spectrum of visible light.
Chlorophyll is a chemical photoreceptor that traps light for photosynthesis in plants.
