the outer electrons which are weakly attracte towards nucleus of a pigment can absorb a photon and gets exited to its unstable higher levels. It releases more energy when it gets stabilized to its normal state. This energy can be trapped by the electron of next pigment molecules. In this way the energy gets transfered from one to other.

How are electrons and protons used during the photosynthetic process?
(From Wikipedia; slightly paraphrased to make it easier to understand.) During the light-dependent stage of photosynthesis, one molecule of the pigment chlorophyll absorbs one photon (unit of light) and loses one electron. This electron is passed to a modified form of chlorophyll (called pheophytin), which passes the electron to a quinone molecule (another pigment), allowing the start of a flow of electrons down an "electron transport chain" that leads to the ultimate reduction of NADP+ to NADPH. In addition, this creates a "proton gradient" across the chloroplast membrane. Its dissipation is used at the same time by "ATP synthase" to make ATP from ADP. The chlorophyll molecule regains the lost electron from a water molecule through a process called photolysis, which releases an oxygen molecule (02).
What happens when a photon from sunlight strikes a chlorophyll a molecule?
When a photon strikes a pigment molecule such as chlorophyll, the energy from the photon is passed to the chlorophyll. This energy then continues to pass between molecules until it hits the reaction center, where the reaction of photosynthesis' glucose creation occurs.
Which molecule is made during the light-dependent reactions?
Photosystems are the light-harvesting units of the thylakoid membrane.Each photosystem is a complex of proteins and other kinds of moleculea and includes an antenna consisting of a few hundred pigment molecules. When any antenna molecule absorbs a photon, the energy is transmitted from pigment molecule to pigment molecule until it reaches a particular chlorophyll a.Only this chlorophyll molecule is the reaction center and the first light-driven chemical reaction of photosynthesis occures.
How does a pigment capture the suns energy?
When a photon hits a pigment, it excites the electrons in one of the double bonds in the pigment. In chlorophylls, these double bonds are the ones that are found closest to the magnesium atom at the centre of the pigment. When one of these electrons is excited by just the right wavelength, i.e. just the right energy of light, it will leave the pigment and evetually enter a series of proteins located on the thylakoid membranes collective known as the photosynthetic electron transport chain. This electron transport chain functions similarly to its animal analog in that it involves a series of redox reactions that use the energy in the electron to pump protons across the thylakoid membrane. This creates a proton concentration gradient across the membrane and ATP synthase can harvest the energy of protons moving down the gradient to make ATPs. This is a brief explanation of how light energy is converted by plants to ATPs.
Will plants die if you don't give water?
Yes and for two reasons id the plant is vascular. One reason is that turgor pressure is not maintained without water and the plant can not hold itself erect then. The second and more important reason is that the plant needs to split water molecules to get replacement electrons when the chlorophyll pigment is excited by photon strike and it's electrons enter photosystem II. Without the replacement of those lost electrons there would be no photosynthesis and the plant would die in short order.
A pigment absorbs a photon only if the energy of the photon is?
Gay.
What happens when light hits a pigment?
When a chlorophyll molecule absorbs a photon of light, Photons strike the "antenna" of the chlorophyll molecule. This causes electrons in the photo-reaction centers that are attached to the antennas to become excited and move to a higher energy level. That's photoexcitation. The valence electrons in Magnesium (part of the chlorophyl molecule) jump to an excited state.
What gets excited when chlorophyll absorbs a photon?
electrons
What happens when carbon dioxide absorbs an IR photon?
The molecule vibrate
What happens when a molecule absorbs a photon of infrared radiation?
When molecules heat up they get more Kinetic energy so they move faster n they collode more n they spread far away from each other thats why they r changed from liquid to gas or from solid to liquid
What absorbs photons?
Matter absorbs photons. Electrons in quantized harmonized orbits of the same energy level as the photon absorp it.
What happens when photon is absorbed by atom?
When an atom absorbs a photon its energy is transferred to outer shell electrons. The result will be the transition of an electron to a higher energy state.

When a molecule absorbs a photon one of the electron is raised in what state?
This electron is in an excited unstable state.
What best explains how green plants absorbs energy from the sun?
A photon strikes electrons in special molecules in the cells A.S.Apex go apex >A<
Does a photon have electrons?
No. A photon is a particle of light. It is massless.
