Photosynthesis -The importance of Illumination/Light

Why do Plants need Photosynthesis? All living things need energy to grow and reproduce. As for plants, they use cellular respiration to produce Adenosine Triphosphate (ATP). ATP is the energy-carrying molecule found in the cells of all living things. This respiration process needs glucose thus photosynthesis. Just like humans eat food to survive, plants make their own “food” through photosynthesis. Moreover, carbohydrates are also needed by the plant to build plant cell structures, like the cellulose cell wall. How does photosynthesis work? In the simplest explanation, it is a process where plants use light, water, and carbon dioxide to make glucose to survive. The complex explanation is that plants take in and use carbon dioxide through tiny holes in a plant’s leaves, flowers, branches, stems, and roots. Water is then absorbed by the roots to make the plant’s food with the presence of lights. You might be wondering by now; How does a plant take carbon dioxide and water to generate food? This is when the light comes in. The energy from light causes a chemical reaction that breaks down carbon dioxide and water to make sugar (glucose) and oxygen. The sugar is then broken down into energy that can be used for the plant’s growth. The oxygen that
