Photosynthesis produces glucose, a simple sugar.

Here's a breakdown:

* Photosynthesis: The process where plants use sunlight, water, and carbon dioxide to create energy (in the form of glucose) and oxygen.

* Glucose: A type of sugar that serves as the primary source of energy for plants and other organisms.

While glucose is the main product of photosynthesis, plants can further convert it into other types of sugars, starches, and complex molecules they need for growth and development.
