Which of the following best describes the overall goal of photosynthesis?

The overall goal of photosynthesis is to convert light energy into chemical energy. This process occurs primarily in plants, algae, and some bacteria, where light energy, usually from the sun, is captured and then used to synthesize glucose from carbon dioxide and water. The chemical energy stored in the bonds of glucose can later be utilized by the organism for growth, reproduction, and other life-sustaining processes.

While the production of oxygen and carbon compounds occurs as part of this process, these are not the primary objectives of photosynthesis. Oxygen is a byproduct released during the light-dependent reactions, and while glucose (a type of carbon compound) is produced, the essential aim is to harness light energy to create usable chemical energy stored in organic molecules. Additionally, while water conservation is important for plant survival, it is not a primary goal of photosynthesis itself. Thus, the main focus is on the transformation of light energy into a form that can be readily utilized by living organisms.
