Explanation
B: Mesophyll Cells of C3 and Bundle Sheath Cells of C4 plants
The Calvin pathway, also known as the C3 cycle or the dark reaction, is a metabolic pathway that is used by all plants to convert carbon dioxide into sugars. In C3 plants, such as wheat and rice, the pathway occurs in the mesophyll cells. In C4 plants, such as corn and sugarcane, the pathway occurs in both the mesophyll cells and the bundle sheath cells. However, in C4 plants, the mesophyll cells initially fix carbon dioxide into a four-carbon molecule, which is then transported to the bundle sheath cells for further processing in the Calvin pathway.
