Photosynthesis Process

Photosynthesis happens in the light. Cellular respiration happens in the dark. In the process of photosynthesis, the plants need sunlight for energy. Photosynthesis is the process that plants use light energy from the sun to make their own food. Cellular respiration is a chemical process plants use to release the stored chemical energy from glucose as usable chemical energy so it can be used by plants.

A plant in the dark will only carry out respiration, but in the light the plant can carry out both respiration and photosynthesis. Plants take in carbon dioxide from the atmosphere. They also release carbon dioxide into the atmosphere, as well as oxygen. All this proves that I agree with Mika.

The sun is the main source of energy. The key is a chemical process called photosynthesis. Photosynthesis is also a chemical reaction. A chemical reaction is a process during which the atoms making up one or more molecules are rearranged into differently shaped molecules. Sunlight captured by the plant during photosynthesis is stored as chemical potential energy within the glucose molecules made by the plant. During photosynthesis, a chemical change occurs in chloroplasts, and plants turn carbon dioxide (CO2) and water (H2O) into glucose and oxygen (O2).

Cellular respiration occurs in EVERY LIVING CELL. Without it, plants would not have access to the energy in the sugar (glucose). Without energy, life cannot be maintained. The process of cellular respiration takes place in the organelles called mitochondria. The glucose molecules enter mitochondria and mitochondria release energy stored in glucose molecules. Made during cellular respiration, ATP provides cells with the energy needed for cell activities. To release the stored energy contained within the food molecules, the organism carries out respiration. Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. Plants take in carbon dioxide from the atmosphere and use it as a source of carbon for the sugars they produce, such as glucose (C6H12O6). Cellular respiration occurs within mitochondria, and like photosynthesis, the process consists of many different ways.

Plants carry out both photosynthesis and cellular respiration. The reactants of photosynthesis are water and carbon dioxide. The products are glucose and oxygen. Light provides the energy required to change inorganic molecules into complex organic molecules. Cellular respiration breaks down complex organic molecules, releasing the energy they contain. The reactants of cellular respiration are glucose and oxygen. The products are carbon dioxide, water, and ATP. All of this information proves why I agree with Mika.
