C3 plants are a type of plant that use a specific photosynthetic pathway to convert sunlight into energy. This process occurs in three main steps, starting with the absorption of carbon dioxide from the atmosphere. The name "C3" comes from the fact that the first stable product formed during photosynthesis contains three carbon atoms. Common examples of C3 plants include wheat, rice, and soybeans. These plants thrive in moderate climates and are most efficient in cool, moist environments. However, they can struggle in high temperatures and dry conditions, as their photosynthetic process can become less efficient. C3 plants are essential for global agriculture and play a significant role in food production.
