Q. If we supply only blue and red lights of the same frequency as sunlight will photosynthesis take place?
The absorbed blue and red lights are most effective for photosynthesis.

Dear Student,

Please find below the solution of your asked query:

Photosynthesis is best in red light and very poor in green light. Chlorophylls absorb the red light and carotenoids absorb blue-green light, but green light is not effectively absorbed by photosynthetic pigments in plants; therefore, light of this color is either reflected by leaves or passes through the leaves. This is why plants are green. Red light is the most effective in photosynthesis because it has exactly the right amount of energy to energize, or excite chlorophyll electrons and boost them out of their orbits to a higher energy level.

Hope this information clears your doubts about the topic.

Keep aksing!!

Regards

Fernando Uribe-Romo of the University of Central Florida has taken the idea further by developing a promising new technology, which he describes in a study published in 2017 in the Journal of Materials Chemistry A. According to a UCF news release, Uribe-Romo's team was able to trigger a chemical reaction similar to photosynthesis in a synthetic material. That material, known as a metal-organic framework or MOF, broke down carbon dioxide in the presence of blue LED lights. The carbon dioxide became two types of harmless organic material: formate and formamides. The best part? Those both just so happen to be forms of solar fuel.
