Suggest how the upper surface of th land plant would differ. |

Answer» nthesis is the process of TRAPPING SUNLIGHT and converting the energy into chemical energy which is then provided as a food source.So the sunlight is trapped through chlorophylls. This is a pigment in the ORGANELLE called the chloroplast. The upper surface of the leaf is open to sunlight where the plants have more chloroplasts CONTAINING more chlorophylls to trap the most amount of sunlight.All these chlorophylls are green coloured and since there is an increased amount of chlorophylls in the upper surface than in the lower surface (to trap more and more sunlight), the upper surface appears to be greener than the lower surface. |
