Plants, in fact, do grow faster under certain colors of light. The reason for this is that chloroplasts can only absorb certain wavelengths of light because of the pigments they contain. There are 2 photosystems in plants called photosystem I and II. PS I absorbs light on the wavelength of 700nm while PS II absorbs 680nm because of their utilization of chlorophyll A and B. These two frequencies are known as the peak absorption points because they are the wavelength at which light is most strongly absorbed. Different forms of chlorophyll and other photosynthetic pigments absorb other frequencies of light, but PS I and PS II are what is used for synthesizing ATP and reducing power which plants use to grow. The visible spectrum of light is between 380-750nm for humans. Therefore PS I and II require red light to perform photosynthesis. As stated before, however, there are other photosynthetic pigments present in plants and other phototrophic species such as bacteria and algae that absorb other pigments. An example of this is the carotenoid pigment that absorbs primarily blue light as do chlorophyll A and B. Blue light contains more energy than red light but for PS I and II and plant growth both are needed. Studies in the 50's showed that the rate of photosynthesis increased under far-red and red light compared to other frequencies.

Green plants will grow SLOWER or not at all under green light. Basically, green is the only brand of light that the plant's chloroplasts doesn't use. That is why it is the only color reflected from the leaf, and is what we see.

Why are plants under the sea a different color than land plants?

The water refracts the light so aquatic plants receive different wavelengths of light than their terrestrial counterparts. Accordingly, the plants have different pigments to trap the different wavelengths which accounts for the difference in color.


Under which color light will plants grow fastest?

Plants grow fastest under blue light, as it is responsible for promoting vegetative growth and chlorophyll production. Blue light also enhances photosynthesis, which is essential for plant growth.


What is the appearance of mold under a black light?

Under a black light, mold may appear as a fluorescent green or yellow color due to the presence of certain compounds that react to the ultraviolet light.


Would plants still be green if there was no sun?

If there were no Sun, and no other source of radiant energy, the plants (and the entire planet) would quickly freeze. And since the color of an object is determined by the color of the light that is reflected by the object, with no light there would be no color, and everything would be black. If we grow plants under artificial light on a space station, then the light on the space station (even if artificial) would be the same kinds of light that we humans prefer, so the plants on the space station would continue to be green.


Do plants grow faster certain colors of light?

Yes they do, certain colors provide certain vitamins/minerals and only sunlight has all the vitamins/minerals needed. Plants get vitamins and minerals from soil, not sunlight. Plants grow slowest under green light because chlorophyll reflects green light (which is why they look green). Plants grow faster under red or blue light. Sunlight is a mixture of red, green and blue light. Plants do get vitamin D from the sun, as do people. Plants do not generate vitamin D from sunlight. Vitamin D is generated in the skin of vertebrates and is necessary for maintaining the bones. The vitamins that plants cannot gather from the soil are generated using a number of different methods. Plants do not require vitamin D.


Does the color of light used on plants affect how well they grow?

Yes, the color of the light will effect how the plant grows. If you put sa plants under a U.V light and the light color is red the plants will grow better than the U. V lgith color that is black.


What is the fluorescence color of amethyst under UV light?

The fluorescence color of amethyst under UV light is typically a light pink or reddish-purple hue.


What color does bleach glow under a black light?

Bleach typically glows a yellow-green color under a black light due to the chemicals present in it that fluoresce under ultraviolet light.


Why do I see red when I look at certain objects or under certain circumstances?

When you see red when looking at certain objects or under certain circumstances, it is because of the way light is absorbed and reflected by those objects. The color red is perceived when an object reflects light in the red wavelength range, while absorbing other wavelengths. This causes our eyes to interpret the object as red.


Can plants live under green light?

no.


Why plant may look green in sunlight but black under red light?

Plants appear green in sunlight because they contain chlorophyll, a pigment that reflects green light. Under red light, plants appear black because chlorophyll absorbs red light for photosynthesis and does not reflect any light back to our eyes. This difference in absorption and reflection properties causes the color variation in different light conditions.
