What are the end products of photosynthesis?

During photosynthesis, plants convert light energy, usually from the sun, into chemical energy stored in glucose. The process primarily occurs in the chloroplasts of plant cells and involves two main stages: the light-dependent reactions and the light-independent reactions (Calvin cycle).

The end products of photosynthesis are glucose and oxygen. Glucose serves as an essential source of energy and is a building block for various organic compounds, while oxygen is released as a byproduct into the atmosphere. This process is crucial for life on Earth, as it provides the oxygen that most organisms need for cellular respiration and generates the glucose that can be used for energy or stored for later use.

The other options do not accurately represent the outcome of photosynthesis. Carbon dioxide and water are substrates used in the process, not the final products. Oxygen and nitrogen, while oxygen is indeed a product, nitrogen does not play a direct role in photosynthesis. Lastly, hydrogen is not a standalone product of the process; instead, it is part of the glucose molecule and does not exist as a separate end product.
