  • green...
  • Plants (using different isoforms of chlorophyll) absorb light maximally at wavelengths of 400-500 nm and 600-700 nm. This translates to violet-blue and orange-red light, respectively. Plants are green because green light is absorbed the most poorly. The green wavelengths bounce off and get captured by cells in our retina.
  • plants absorb blue light best. Check the sky, what color is the sky? it is blue. Photosynthesis takes place more rapidly at noon time than when the sun is setting. Plants cannot absorb green light because they contain chlorophyll which is green.
