WebAtrazine selectively kills target weeds, interfering with the plants growth and causes the plant to die. Atrazine works by interfering with photosynthesis. Photosynthesis— unique to green, living plants—happens when light energy is converted to chemical energy needed for food production. WebThe energy efficiency of photosynthesis is the ratio of the energy stored to the energy of light absorbed. The chemical energy stored is the difference between that contained in …

WebThird, rates of photosynthesis in bright sunlight sometimes exceed the needs of the plants, resulting in the formation of excess sugars and starch. When this happens, the regulatory mechanisms of the plant slow down the process of photosynthesis, allowing more absorbed sunlight to go unused. WebBesides introducing fixed carbon and energy into ecosystems, photosynthesis also affects the makeup of Earth’s atmosphere.
