What process is primarily responsible for producing glucose and oxygen in plants?

The process responsible for producing glucose and oxygen in plants is photosynthesis. This process takes place primarily in the chloroplasts of plant cells, where light energy from the sun is captured by chlorophyll. During photosynthesis, plants take in carbon dioxide from the air and water from the soil. Using the energy absorbed from sunlight, they convert these inputs into glucose, a type of sugar that serves as a source of energy and building blocks for growth. Oxygen is produced as a byproduct of this chemical reaction and is released into the atmosphere.

Photosynthesis is crucial for plant life and also plays a significant role in supporting other life forms on Earth, as it provides the oxygen necessary for respiration and forms the base of the food chain for many ecosystems.
