Show Hint
C3 plants = Random mesophyll.
C4 plants = Wreath-like (Kranz) bundle sheath.
This anatomy is the reason why \(C_4\) plants are so productive in tropical climates!

The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
The question asks to identify the group of plants characterized by a specific leaf internal structure called "Kranz anatomy," which is related to their photosynthetic pathway.
Detailed Explanation:
• What is Kranz Anatomy?
"Kranz" is German for "wreath" or "halo."
In these plants, the vascular bundles are surrounded by a ring of large, chlorophyll-rich Bundle Sheath Cells, which in turn are surrounded by Mesophyll Cells.
• Function in C4 Plants:
This anatomy allows for the spatial separation of the two stages of photosynthesis:
1. Mesophyll cells fix \(CO_2\) into 4-carbon acids using PEP carboxylase.
2. These acids move into the bundle sheath cells, where they release \(CO_2\) at high concentrations for the RuBisCO enzyme to fix in the Calvin cycle.
• Advantages:
By concentrating \(CO_2\) around RuBisCO, \(C_4\) plants (like Maize, Sugarcane, and Sorghum) minimize photorespiration and can perform efficiently in hot, dry, and high-light environments.
Step 2: Final Answer:
Kranz anatomy is the structural hallmark of \(C_4\) plants.
