How Plants Acquire Their Energy Photosynthesis is the process by which plants convert energy from the sun. It is the process that allows plants to create organic molecules that they use as fuel. Here is how it works. The molecules of chlorophyll contained in the chloroplasts absorb energy in the form of light from the sun. Some plants need more sunlight than others, but all need at least a little. Instead of taking in oxygen and breathing out carbon dioxide like animals do, plants take in carbon dioxide from the atmosphere. Plants absorb water from the ground up through their roots. During photosynthesis, the energy from the sun splits the water molecules into hydrogen and oxygen.

Introduction Introduction. 1  Plants and other photosynthetic organisms are experts at collecting solar energy, thanks to the light-absorbing pigment molecules in their leaves. 2  As it turns out, some of the light energy absorbed by pigments in leaves is converted to a different form: chemical energy. Light energy is converted to chemical energy during the first stage of photosynthesis, which involves a series of chemical reactions known as the light-dependent reactions. In this article, we'll explore the light-dependent reactions as they take place during photosynthesis in plants. We'll trace how light energy is absorbed by pigment molecules, how reaction center pigments pass excited electrons to an electron transport chain, and how the energetically downhill flow of electrons leads to synthesis of ATP and NADPH.

WHAT ABOUT PHOTOSYNTHESIS AND WHY IS IT IMPORTANT? During photosystem I, light is absorbed. Electrons move from chlorophyll A molecules to another primary electron acceptor. The electrons lost from photosystem I are replaced by electrons that have passed through the electron transport chain from photosystem II. When electrons start losing their energy from photosystem II they move onto Photosystem I.

Photosynthetic Cells Different pigments respond to different wavelengths of visible light. Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly. In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.

What is the primary photosynthetic pigment in plants? Chlorophyll, the pigment found in plants, some algae, and some bacteria that gives them their green color and that absorbs the light necessary for photosynthesis. Chlorophyll absorbs mainly violet-blue and orange-red light.hlorophyll b is an accessory pigment present in plants and other complex photosynthetic cells; it absorbs light energy of a different wavelength and transfers it to chlorophyll a for ultimate conversion to chemical energy. Other chlorophylls, of minor importance, are found in some bacteria.

- Answer 1: Photosynthesis is the ability of plants to absorb the energy of light, and convert it into energy for the plant. To do this, plants have pigment molecules which absorb the energy of light very well. The pigment responsible for most light-harvesting by plants is chlorophyll, a green pigment.The green color indicates that it is absorbing all the non-green light-- the blues (~425-450 nm), the reds and yellows (600-700 nm).he pigment responsible for most light-harvesting by plants is chlorophyll, a green pigment.

Photosynthesis - Part I: The Sun and Light Even when light gets to a plant, the plant doesn't use all of it. It actually uses only certain colors to make photosynthesis happen. Plants mostly absorb red and blue wavelengths. When you see a color, it is actually a color that the object does NOT absorb. In the case of green plants, they do not absorb light from the green range. We already spoke about the structure of chloroplasts in the cells tutorials.

- The absorbed energy is transferred to the reaction center chlorophylls, P 680 in photosystem II, P 700 in photosystem I. Absorption of 1 photon of light by Photosystem II removes 1 electron from P 680. With its resulting positive charge, P 680 is sufficiently electronegative that it can remove 1 electron from a molecule of water.
