The process of plants creating glucose
Explanation:
Photosynthesis is how plants create their own food. Using a mixture of sunlight, water, and carbon dioxide they are able to produce glucose and releases oxygen as a byproduct.
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.

The process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
