### Step-by-Step Solution: 1. **Understanding RUBISCO**: RUBISCO (Ribulose-1,5-bisphosphate carboxylase/oxygenase) is an enzyme that catalyzes the first major step of carbon fixation in photosynthesis. It can act as both a carboxylase (fixing CO2) and an oxygenase (fixing O2). 2. **C4 Plants Overview**: C4 plants have a specialized photosynthetic pathway that allows them to efficiently fix carbon dioxide. They possess a unique anatomical structure known as Kranz anatomy, which is characterized by a specific arrangement of mesophyll and bundle sheath cells. 3. **Kranz Anatomy**: In C4 plants, the mesophyll cells capture CO2 and convert it into a four-carbon compound (hence the name C4). This compound is then transported to the bundle sheath cells, where it releases CO2 for the Calvin cycle. ...
