The second resarch

 

I have the  plant and grew in the garden  and I watching the leaves of the plant in the garden growing  has been already bright green because the sun's shine alight onto the plant that is why the leaves is growing green bright. 

Leaves and growing fresh grass are green because they contain a natural pigment known as chlorophyll. Chlorophyll takes the energy of sunlight and uses it to convert carbon dioxide and water into chemical energy, in the form of glucose, or natural sugar, which allows the plant to grow. This process is called photosynthesis. Chlorophyll absorbs the long wavelengths (red) and short wavelengths (blue) of the light, but the green light is reflected, making the grass and leaves appear green.[30] Chlorophyll does not absorb green light because it first arose in organisms living in oceans where purple halobacteria were already exploiting photosynthesis. Their purple color arose because they extracted energy in the green portion of the spectrum using bacteriorhodopsin. The new organisms that then later came to dominate the extraction of light were selected to exploit those portions of the spectrum not used
