- 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).

Biology book1 Wavelengths absorbed by chlorophyll and other photosynthetic pigments generate electrons to power photosynthesis. All photosynthetic organisms have chlorophyll a which absorbs violet-blue and reddish orange-red wavelengths. Chlorophyll a reflects green and yellow-green wavelengths.Accessory photosynthetic pigments, including chlorophyll b and beta-carotene, absorb energy that chlorophyll a does not absorb.avelengths absorbed by chlorophyll and other photosynthetic pigments generate electrons to power photosynthesis.

- Answer 2: The color or wavelength of light does affect photosynthesis, which is how plants can basically create their own food.Essentially, the reason why plants are green is they are absorbing the other wavelengths of light but reflecting back the green. The wikipedia page on photosynthesis goes into a lot more detail.

Chlorophyll: Absorbing Light Energy for Photosynthesis A pigment is a compound that absorbs a particular wavelength of visible light. Chlorophyll is a green pigment contained in thylakoid membranes of chloroplasts that is used in photosynthesis by plants.

What Happens When a Chlorophyll Molecule Absorbs Light? A Photon of Light Excites the Chlorophyll Molecule. When a chlorophyll molecule absorbs light, the process of photosynthesis, or the transfer of light into sugar, begins. Chlorophyll is a green liquid inside one part of a plant cell: the chloroplast. When light hits the chlorophyll molecule, it becomes excited. This energy passes through other chlorophyll molecules, and into the reaction center of Photosystem II: this is the location of the first stage of photosynthesis, and the electron transport chain. For each photon of light that enters and excites a chlorophyll molecule, one electron is released from the reaction center of Photosystem II.

Chapter 6: Photosynthesis Red (660 nm) and blue (440 nm) lights are required for the process of photosynthesis. Low rate of photosynthesis from the plant is expected if a plant is placed into an environment where only green light is received. Chlorophyll reflects green wavelength (550 nm) and absorbs the blues and the reds most.

Photosynthesis Respiration and Plant Growth Less than half of the solar energy reaching the earth can be used by plants for photosynthesis. This light spectrum is from 400-700 nm and is termed Photosymthetically Active Radiation (PAR). This light is in the blue (400-500 nm) and red (600-700 nm) spectrum.

Plants: Photosynthesis Through the process of photosynthesis, sun light is absorbed by plants and converted into chemical energy. Using that chemical energy, the plants are then able to absorb carbon dioxide from the atmosphere and turn it into food for themselves.hrough the process of photosynthesis, sun light is absorbed by plants and converted into chemical energy.

What Two Colors of Light Drive Most of Photosynthesis? The red and violet-blue light emitted from the sun are absorbed by the chlorophyll and used to drive most of photosynthesis. The green light is not absorbed and then reflected back which gives the leaves of plants their green color, according to the Central Michigan University. Keep Learning.

Light Absorption for Photosynthesis Photosynthesis depends upon the absorption of light by pigments in the leaves of plants. The most important of these is chlorophyll-a, but there are several accessory pigments that also contribute.

Chlorophyll: Absorbing Light Energy for Photosynthesis Photosynthesis is driven by the use of a pigment or molecule that absorbs a specific wavelength of energy. In this case, the primary pigment is chlorophyll, which is a pigment that absorbs blue and red wavelengths while reflecting green wavelengths.he electromagnetic spectrum is the range of wavelengths from the radio waves of your car stereo to high-energy gamma rays. Chlorophyll and other pigments absorb specific visible wavelengths of the electromagnetic spectrum. The visible light is literally the colored wavelengths that are visible to your eyes.

How will a green plant grow with green light? These absorb mostly red and blue light, and absorb green the least. If only exposed to green light, the plant will not grow as much as if it were exposed to a full spectrum of colors, or as much as if it were exposed to red or blue light.hlorophyll absorbs all the different coloured wavelengths, but leaves green as the colour it reflects and as the colour we see.  Therefore, white light is best to grow plants under because green light doesn't do much of anything for photosynthesis.

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 wavelengths of light do plants use for photosynthesis? plants use red and blue light for photosysnthesis, green is reflected back by the chloroplasts in the leaves-green light is therefore not used for photosysnthesis.

- Chlorophyll b: This molecule has a structure similar to that of chlorophyll a. It absorbs light of 453nm and 642 nm maximally. It is not as abundant as chlorophyll a, and probably evolved later. It helps increase the range of light a plant can use for energy.

Biology, Answering the Big Questions of Life/Photosynthesis Light is a form of energy. The form of light that plants capture, as well as the light that you and I can see, is called visible light. The white light that shines on Earth from the sun is actually composed of light of many different colors.

How does electromagnetic spectrum relate to photosynthesis? Plants absorb energy only from the red and blue ends of the visible electromagnetic spectrum. They reflect the unused green light to our eyes. Plants use visible light (400 nm to 700 nm) for growth and photosynthesis. The wavelength of red light is about 650 nm. Green light has a wavelength of about 510 nm, and the wavelength of blue light is about 475 nm. Photosynthesis depends on on the absorption of light by pigments in the leaves of plants.

- shortest wavelength), and plants possess pigments that can absorb light in specific regions of the spectrum (see Figure 1). One of the green pigments that absorbs light for use in photosynthesis is called “ chlorophyll a”; it readily absorbs violet/blue and red light but not much of the lighter blue, and green and yellow light.

Green light: Is it important for plant growth? Plants grown with 50 percent green and 50 percent red light were approximately 25 percent shorter than those grown under only red light, but approximately 50 percent taller than all plants grown under more than 25 percent blue light (Photo 2).reen light is considered the least efficient wavelength in the visible spectrum for photosynthesis, but it is still useful in photosynthesis and regulates plant architecture.

Biology book1 The color of the pigment comes from the wavelengths of light that are reflected, or in other words, those wavelengths not absorbed. Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects. This is why plants appear green to us.
