Does the light color spectrum and frequency matter for photosynthesis
Leaves reflect and derive little energy from many of the yellowand green rays of the visible spectrum.
Color & Light Effects on Photosynthesis | Hunker
There are four things that are required by the plant before it can carry out photosynthesis, they are light, chlorophyll, carbon dioxide and water ....
Life on our planet has adapted to the light from our Sun. Plant photosynthetic pigments, for example, use the Sun's abundant visible light — most strongly absorbing in the blue and red part of the spectrum, which is why they appear green in reflected light.
Affect of Different Colored Lights on Photosynthesis
Yet the red and blue parts of thelight spectrum are the most important energy sources for plants, and plantsrequire more rays from the red range than from the blue.
You know that too much sunlight can damage your skin, fade colors in clothing and cause other problems. Therefore it shouldn't be surprising to find out that sunlight also causes chlorophyll molecules to break down. In fact, during the summer, green plants must continually create new chlorophyll to replace what has been destroyed. This creation, or synthesis, of chlorophyll requires not only sunlight but also warm temperatures, so you can see why fall's cooler weather encourages our trees' leaves to begin showing colors other than green.
Effect of Different Colored Lights on Photosynthesis
You will also do an absorption spectrum of the photosynthetic pigments extracted
from Elodea and determine if there is a correlation between the rates of photosynthesis
under the different colored bulbs, the wavelengths of light that those filters transmit, and
the optimum wavelengths of light absorbed by the plant.
Biol 171L – FA15 Effect of Light Color on Photosynthesis 7-5
You will work in groups, as directed by your TA, and each group will take one part of the
If the wavelength available to the plant affects
photosynthesis, then we would expect to see a difference in the photosynthetic rates
produced by the different colors of light, and therefore a measurable difference in the
amount of O2 produced during photosynthesis.
Total or GROSS photosynthesis, is the total amount of carbon fixed or oxygen
released by a plant in the light.

What color in the visible spectrum has the shortest wavelengths?
Plants are able to satisfy their energy requirements by absorbing light from the blue and red parts of the spectrum.
is known as the visible spectrum
Our new 100 watt lights, & , model numbers MLH100 & CC100 respectively come with a straight 3-year warranties.
Lighting Spectrum and Photosythesis - Lighting - …
Pigments absorb lightenergy in a narrow band we know as the visible light range (400-700 nm).
Color vision Visible spectrum .
So, while different colors of light effect don´t cause flower petals to be a certain color, they do determine when and how the plant will grow (blue light), and when it will flower and produce fruit (red light). So, different colors of light are very important to plants!
Light Spectrum and Photosynthesis? | Yahoo Answers
As days begin to shorten in the late summer and early fall, the blue light that dominated the spectrum of sunlight is slowly overtaken by red light. Many ripened fruits and vegetables are harvested in the late summer and early fall. Red light is needed for this purpose: flowering and the production of fruit.
How Does Color Spectrum Affect Growing Marijuana Plants?
But plants aren't the only organisms that use sunlight on Earth. Kiang studies various photosynthetic bacteria that have an entirely different set of pigments for absorbing light. She compares the spectra from these pigments to try to understand what mechanisms drive the evolution of the light harvesting ability.
Effect or Light color on photosynthesis | Academic …
I don't believe the color of the petals of a flower care much what color the ambient light is, mainly because nearly all plants spend most of their time in white light (white being the color of sunlight). Yellow or orange flowers are colored with carotenoid pigments, and red, blue, or purple flowers use anthocyanin pigments, and these pigments are coded for in the plant's genes. It would have a hard time changing color even if it had reason to.
Light is part of the electromagnetic spectrum
While sunlight contains all color of light, the sunlight of the long days of spring and the even longer days of summer is predominately blue. This is the time of year when plants that have been dormant over the winter start to grow and seeds begin to germinate. Plants use blue light for exactly these actions: growth of stems, stalks, leaves and the germination of seeds and seedlings.
it gets the same amount of light from the red end of the spectrum
What this tells us is that photosynthesis is not a one-size-fits-all solution, and the pigments used on a different planet will likely be adapted to local conditions. To help imagine what these alien pigments might be, Kiang has started the Biological Pigments Database. This contributes a biological component to the NASA Astrobiology Institute Virtual Planetary Laboratory’s Spectral Database, which brings together stellar radiation spectra, molecular line lists for atmospheric radiative transfer, and now biological pigments.
