C4 plants are a group of plants that have a unique photosynthesis process, allowing them to efficiently capture carbon dioxide. This adaptation helps them thrive in hot and dry environments, where water loss is a concern. Examples of C4 plants include maize, sorghum, and sugarcane. In C4 photosynthesis, carbon dioxide is initially fixed into a four-carbon compound, which is then converted into sugars. This process minimizes photorespiration, a wasteful reaction that occurs in some plants, particularly under high temperatures. As a result, C4 plants can produce more energy and grow better in challenging conditions.
