Some examples of C3 plants are beans, rice, wheat and potatoes. Crops that are grown in temperate regions, as well as all types of woody trees, are considered to be C3 plants. C3 plants are defined by their usage of only the C3 photosynthesis pathway to break down inorganic CO2.
As of 2014, C3 plants make up approximately 85 percent of all plants found in the wild. Crops and trees belonging to the C3 category typically have leaves with large air spaces. Other types of plants that are found in nature can be categorized into C4 and CAM plant types.
