C4 plants are a group of plants that utilize a unique photosynthetic pathway to efficiently fix carbon dioxide into a four-carbon compound, instead of the typical three-carbon compound seen in C3 plants. This adaptation allows them to minimize photorespiration and thrive in high light, high temperature, and low carbon dioxide environments. The efficiency of this pathway makes C4 plants particularly resilient to climate change impacts, as they can better cope with increased temperatures and variable water availability.
congrats on reading the definition of C4 plants. now let's actually learn it.
