Which is a c4 plant? a. pineapple b. cactus c. pea d. corn

The correct answer is D. Corn

Explanation:

In plants, C4 or C4 Carbon Fixation refers to a complex photosynthesis process that occurs in some plants, this process involves multiple steps that allow plats to fix and process carbon, without photorespiration as it occurs in most photosynthesis processes. C4 plants contain special cells and structures that allow them to do the Carbon Fixation processes. Additionally, this occurs mainly in plants that grow in tropical or elevated temperatures. Examples of C4 plants include sugarcane and corn as they follow the C4 Carbon Fixation in photosynthesis. According to this, it is Corn the one that is a C plant.
