The image illustrates the process of photosynthesis and its function.
Overall, it is clear that process is started by absorbing green wavelength from the sun and carbon dioxide through stomata, and ending with release of oxygen.
To begin, the green look of plants is made by absorbing green wavelength from sun by the process of chlorophyll. There are a lot of opening are present on the surface of leaf which allows the entrance of carbon dioxide. Meanwhile, water which is present in roots is combined with carbon dioxide and wavelength to make sugar for plants. And in this way oxygen is entered into environment.
Further more, the water level in plant is balanced by a process called transpiration. In this procedure, oxygen and water vapors are moved out from the leaf through stomata. More ever, the extra sugar as a starch is stored in roots of plants during photosynthesis which provides energy to plants.
