Which of the following best describes the process of photosynthesis?

• A. The conversion of light energy into chemical energy by plants
• B. The breakdown of glucose for energy in animals
• C. The movement of water through a plant's roots
• D. The reproduction process in flowering plants

Answer: (A)

The process of photosynthesis is best described as the conversion of light energy into chemical energy by plants. During photosynthesis, plants use sunlight to convert carbon dioxide from the air and water from the soil into glucose, a type of sugar that serves as food for the plant. This process takes place mainly in the chloroplasts of plant cells and results in the production of oxygen as a byproduct. The energy captured from sunlight transforms into chemical energy stored in the bonds of glucose molecules. The other options do not accurately capture the essence of photosynthesis. While the breakdown of glucose for energy in animals pertains to cellular respiration and describes how animals use the energy stored in glucose, it is not the process of photosynthesis. The movement of water through a plant's roots primarily refers to water uptake and transport rather than the transformation of energy. Lastly, the reproduction process in flowering plants does not involve energy conversion but rather pertains to the life cycle and reproductive strategies of plants. Thus, the focus on energy transformation accurately delineates photosynthesis from these other processes.
