Sunlight and artificial light both have their places in ..
"The second critical feature of the photosynthetic apparatus," Wrighton emphasized, is that "in order to achieve high solar conversion efficiency, the formation of a single fuel molecule will involve the energy from more than one photon." The ratio of photons to electrons released will probably be one to one in any system—as it is in nature—but there must be a way to harness the energy from several of these freed-up electrons to produce a chemical transformation. "If a one-photon mechanism were operative in nature, the process would be doomed to low efficiency," he explained, because a single photon that would break down H2O would have to be in the blue wavelength range, and "sunlight does not contain much energy of blue light, or of shorter wavelengths." Nature's way of aggregating and using more than one photon of the energy that is abundant, throughout the entire optical wavelength spectrum, is photosynthesis.
What Kinds of Light Do Plants Grow Better In
Farmers can use their knowledge of these limiting factors to increase crop growth in greenhouses. They may use artificial light so that photosynthesis can continue beyond daylight hours, or in a higher-than-normal light intensity. The use of paraffin lamps inside a greenhouse increases the rate of photosynthesis because the burning paraffin produces carbon dioxide, and heat too.
Wrighton's presentation, "Photosynthesis—Real and Artificial," was a closely reasoned, step-by-step discussion of the crucial stages in the chemical and molecular sequence of photosynthesis. His colleagues in the session were chosen for their expertise in one or another of these fundamental specialized areas of photosynthesis research. By the end of the session, they had not only provided a lucid explanation of the process, but had also described firsthand some of the intriguing experimental data produced. Douglas Rees of the California Institute of Technology (on the molecular details of biological photosynthesis), George McLendon of the University of Rochester (on electron transfer), Thomas Mallouk of the University of Texas (on the arrangement of materials to facilitate multielectron transfer chemistry), and Nathan Lewis of the California Institute of Technology (on synthetic systems using liquid junctions) all supplemented Wrighton's overview with reports about findings in their own area of photosynthesis research.
Growing plants indoors under supplemental lighting
In the case of research on artificial photosynthesis, such work could lead to the economical production of an alternative to the dwindling supply of fossil fuels. And a further benefit might be a reduction in the sulfurous products emitted by the combustion of carbon-based fuels. Wrighton explained that these fuels are themselves "the result of photosynthetic processes integrated over the ages." It must be kept in mind that long before plants developed the ability to produce molecular oxygen as a byproduct of photosynthesis, they were always about their real business of converting carbon dioxide from the atmosphere into carbohydrates for their own sustenance. In fact some of these anaerobic plants still exist today in certain specialized ecological niches. The system for photosynthesis evolved to its present state during the earth's natural history, and it exploits materials that are naturally abundant and inexpensive, Wrighton pointed out. As designed by nature, it is the ultimate recycling process—since it uses the planet's two most abundant resources, CO2 and H2O, providing fuel and breaking down a pollutant.
Does LED lighting work for artificial plant light
I think this because the plant may use up all of the carbon dioxide (Sodium hydro carbonate) and the plant can have as much light as it needs but if it does not have any carbon dioxide it will not be able to photosynthesise....

Light is a very important factor in the rate of photosynthesis, in my project I am going to test that plants do need light in order to photosynthesise.
