Explanation:
Photosynthesis is the process in which leaves absorb solar energy and use it to convert CO2 and H2O into chemical energy called glucose(food).
As photosynthesis is dependent on the sunlight energy therefore it has been suggested to scientists that they should genetically engineer a plant to have black leaves as black color absorbs more sunlight than any other color. Black color absorb all the wavelength of sunlight and it does not reflect any.
So more light absorbance capability of black color should be the reason behind this idea.
