What role do plant pigments play in the process of photosynthesis?
Pigments are able to absorb specific wavelengths of light which power photosynthesis. Chlorophyll, which is green, absorbs all wavelengths except green. Each photon excites an electron in the light harvesting complexes of a photosystem in a chlorophyll molecule, eventually producing ATPs. Other pigments will be a different color and will be able to absorb other wavelengths, maximizing energy absorbency when the sun's rays change.
What are the main energy storing products of each phase of photosynthesis?
It is the pigment. It is absorbing light.
What pigment traps the energy for photosynthesis?
There is a wide range of pigments that are used for photosynthesis. However, chlorophyll is responsible for using obtained light energy to excite electrons to move through the transport chain. Many pigments are only capable of transferring energy to chlorophyll, but they are important because they increase the spectrum of the frequencies of light of which the organism can use to photosynthesize. These pigments are called accessory pigments. For a more detailed explanation of these pigments, view the attached link below.
Why does chlorophyll make plant leaves appear green?
Chlorophyll is a complex biomolecule containing magnesium. The molecule contains special ring shaped structures that capture preferred wavelengths of light. Green is not "captured" so it is reflected back to our eye. I do know that plants may contain modified chlorophyll and other pigments to take advantage of the type of light available to them. One example are sea plants where only certain wavelengths of light may reach specific depths and the plants have evolved to capture this light for energy. "We can also look at this from another angle. Why does chlorophyll reflect ("throw away") green light, which is the most abundant color in sunlight, and utilize instead the weaker reds and blue? Scientists theorize that it may have been because competing organisms were absorbing much of the green wavelengths billions of years ago, so algae (the earliest plants) reflected the green away and instead absorbed the red and blue hues that remained. Early in Earth's history, the oceans were dominated by archaea, bacteria-like organisms that are often purple in color, due to a pigment used to create energy from the sun in a process analogous to photosynthesis (but completely differently at the chemical level). As algae came along, they would have found a beneficial niche by utilizing the unused red and blue wavelengths (and reflecting the green). If you compare the absorption spectra of chlorophyll (plants) and retinal (the pigment in archaea), they are mirrors of each other, which supports this theory. Why archaea never evolved into complex organisms like algae did into plants and trees is not known (to me, at least), but another roll of the evolutionary dice might have led to large, purple archaea-trees that could outcompete plants (since plants use only the weaker red/blue wavelengths). Today, archaea ancestors remain as microorganisms that tend to inhabit extreme environments (geysers, salt ponds, etc.) where their purple (and red) colors can still be seen.

Where in chloroplasts is light energy absorbed?
chloroplast have membrane bound sac like structures piled up on top of each other called thylakoids which have chlorophyll(pigment having "Mg"ion) filled in them, this pigment is primarily responsible for absorption of photons of light
How does it benefit a plant to have Multiple pigments?
different pigments have different wavelengths of light which it can absorb... so helps to increase the range of wavelengths of light that can be absorbed... also helps to avoid photo oxidation of the main plant pigment..
What physical phenomenon is causing each dye to absorb light of one or more colors and transmit light of other colors?
In a spectrometer, each dye will absorb light of certain colors and transmit light of other colors because of the nature of the atoms of the object and the frequency of the light. If the frequency of the light is the same as the frequency that the electrons in the atoms are vibrating, then the light will be absorbed and transferred into vibrational motion.
What kind of pigment will only absorb one frequency of light?
None, such a pigment would be utterly useless, biologically. Even rhodopsin in your rods, which process black and white and are primarily used for change detection, absorbs multiple frequencies of light. Would it make sense for you to use a ton of different pigments that each absorb one wavelength, instead of having a few that absorb a wide range of wavelengths? I would attach a diagram of the absorption spectra for rhodopsin, but I think my Professor would get mad about copyrights.
Is every plant green in color if not so give reason?
Some plants are not green because each plant has pigments that use to trap different wavelengths. For example, each plant contains chloroplast that traps light energy. The chloroplast contains chlorophyll, which are the green pigment that absorb the energy of the sun.
An element is selective in the frequency of light it will absorb This selectivity is due to its?
Every element can only absorb certain wavelengths of light because of how the electrons are positioned around the nucleus. There is a fixed number of energy levels that each electron may move to, and each move will only occur if a specific amount of energy is absorbed. Thus each element, having differing electron orbital states can only absorb certain frequencies of light.
How is light capture by living things?
"Molecules, when struck by a wave or photon of light, reflect some of its energy back out, or it can absorb the energy, and thus enter into a higher energy or excited state. Each molecule absorbs or reflects its own characteristic wavelengths of light. Molecules that have evolved to absorb wavelengths in the visible region of the spectrum very well are called pigments."(http://202.114.65.51/fzjx/wsw/website/mit/ps/physics.html)
What is photosynthetic pigment?
photosynthesis pigments are molecules that absorb light energy. each pigments absorbs rang of wavelength in the visible region and own distinct peak. and other wavelength's are reflected
Does each colour or light have different velocities?
No, but they have different wavelengths.
Why do plants not grow well in green light?
Plants have mesophyll cells that contain chloroplasts. In most green plants, chlorophyll a, chrlorophyll b (an accessory pigment), and carotenoids are the dominant photopigments. Each pigment is able to absorb the photons of light energy from sunlight and use it to complete photosynthesis. Chlorophyll a absorbs most energy from wavelengths of violet-blue and orange-red light and chlorophyll b absorbs mainly blue light. However, no photopigments in green plants are able to absorb green light. Thus, light not absorbed is reflected by the pigments, allowing the plants to appear the color green. When placed under a green light source, the pigments do not receive a sufficient amount of light energy to disrupt the reaction center of the photosystems essential for photosynthesis to occur.
What role do plant pigments play in the process of photosynthesis?
Pigments are able to absorb specific wavelengths of light which power photosynthesis. Chlorophyll, which is green, absorbs all wavelengths except green. Each photon excites an electron in the light harvesting complexes of a photosystem in a chlorophyll molecule, eventually producing ATPs. Other pigments will be a different color and will be able to absorb other wavelengths, maximizing energy absorbency when the sun's rays change.
What must happen to all wavelengths of light?
There a couple things that must happen to all wavelengths of light so that a substance can reflect white. The substance needs to be able to reflect each wavelength equally and the wavelengths must hit it at the same time.
What are the main energy storing products of each phase of photosynthesis?
It is the pigment. It is absorbing light.
