Why do certain colors of light support photosynthesis while others do not?
The pigments involved (e.g. chlorophyll in green plants, phycoerythrin in red algae) only absorb photons of certain energies and reflect others. This is due to the elements in the pigment molecule and how they are bound.
Electrons within certain chlorophyll molecules are elevated to a higher energy level when sunlight strikes a?
strikes the photosystems that consist of many secondary chlorophyll and b karotenes which pass the energy to the reaction centre which is a primary chlorophyll.
What happens when plants have less chlorophyll?
Plants that are unlucky enough to loose all of their chlorophyll will not be able to produce glucose through photosynthesis and will die. This is happens if the entire plant looses chlorophyll; there are other examples of plants (such as white variegated ones) where only certain portions of the leaf have no chlorophyll, in these instances the food is produced and distributed from the areas that do contain chlorophyll to those which don't.
What does a Lewis dot show?
Lewis dot structures show how an atom's electrons work together in a certain molecule. They also show what a certain molecule will look like.
What is the name given to the green pigment found in the chloroplast of certain leaf cells?
The green pigment in chloroplast is chlorophyll.
What happens in photopigments when they absorb photon energy?
Photosystem's electron travel through the electron transport chain(etc) where ATP is produced and then back to the photosystem. In non-cyclic photophosphorylation, Photosystem II electron then is absorbed by photosystem I, photosystem I electron used to form NADPH and photosystem II gets its electron from photolysis of water. For you unfortunate children using Novanet: They move through an electron transport chain to photosystem 1.
What is the organelle that carries out the process of photosynthesis?
chloroplasts, it contains chlorophyll, a green pigment, which helps to absorb sunlight needed to carry out photosynthesis. CHLOROPHYLL. : )

In what living organism would you find chlorophyll?
Chlorophyll is a type of pigment which is found in certain plants. Some plants which contain chlorophyll include algae and plants. Chlorophyll is green in color and accounts for most of the green found in plants.
What is Removing an electron from an atom called?
The process of removing an electron from something is called either oxidation or ionization. Ionization is the process of converting an atom or molecule by changing the number of electrons. In certain chemical reactions, the oxidation state of an atom or molecule is changed, and this is known as oxidation. See more details in the Web Links to the left of this answer.
What converts sunlight into sugars?
Photosynthesis that is where The energy-fixing reaction of photosynthesis begins when light is absorbed in photosystem II in the thylakoid membranes. The energy of the sunlight, captured in the P680 reaction center, activates electrons to jump out of the chlorophyll molecules in the reaction center. These electrons pass through a series of cytochromes in the nearby electron-transport system. After passing through the electron transport system, the energy-rich electrons eventually enter photosystem 1. Some of the energy of the electron is lost as the electron moves along the chain of acceptors, but a portion of the energy pumps protons across the thylakoid membrane, and this pumping sets up the potential for chemiosmosis. The spent electrons from P680 enter the P700 reaction center in photosystem I. Sunlight now activates the electrons, which receive a second boost out of the chlorophyll molecules. There they reach a high energy level. Now the electrons progress through a second electron transport system, but this time there is no proton pumping. Rather, the energy reduces NADP. This reduction occurs as two electrons join NADP and energize the molecule. Because NADP acquires two negatively charged electrons, it attracts two positively charged protons to balance the charges. Consequently, the NADP molecule is reduced to NADPH, a molecule that contains much energy. Because electrons have flowed out of the P680 reaction center, the chlorophyll molecules are left without a certain number of electrons. Electrons secured from water molecules replace these electrons. Each split water molecule releases two electrons that enter the chlorophyll molecules to replace those lost. The split water molecules also release two protons that enter the cytoplasm near the thylakoid and are available to increase the chemiosmotic gradient.

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.
Why are plants steams green?
Plants are green because they have a substance called chlorophyll in them. Understanding why chlorophyll is green requires a little biology, chemistry and physics. If we shine white light on chlorophyll, its molecules will absorb certain colors of light. The light that isn't absorbed is reflected, which is what our eyes see. A red apple appears red because the molecule of pigment in the apple's skin absorbs blue light, not red. Thus, we see red. Chlorophyll molecules absorb blue light and some red light. The other colors are reflected resulting in the green color that we associate with plants. Plants get their energy to grow through a process called photosynthesis. Large numbers of chlorophyll molecules acts as the antenna that actually harvest sunlight and start to convert it in to a useful form. Here's where the absorbent properties of the chlorophyll molecule come into play. It turns out that eons of evolutionary design have matched the absorbance of chlorophyll to the actual color of the sunlight that reaches the leaves. Sunlight consists of primarily blue and red light mixed together, which are exactly the colors that chlorophyll molecules like to absorb. Light is a form of energy, so the chlorophyll is able to harvest the sunlight with little waste.
