Question:
The Kranz anatomy is associated with which type of photosynthesis?
The Kranz anatomy is associated with which type of photosynthesis?
Show Hint
"Kranz" is German for "wreath." Look for this wreath-like cell arrangement in $C_{4}$ plants like maize and sugarcane.

- $C_{3}$ pathway
- $C_{4}$ pathway
- CAM pathway
- Both $C_{3}$ and CAM
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Kranz anatomy is a specialized leaf structure where mesophyll cells are clustered around bundle-sheath cells in a wreath-like fashion.
Step 2: Meaning
This anatomical arrangement allows for the spatial separation of carbon fixation and the Calvin cycle, which minimizes photorespiration.
Step 3: Analysis
$C_{3}$ plants lack this specialized structure. CAM plants separate processes by time, not space. $C_{4}$ plants utilize Kranz anatomy to efficiently fix $CO_{2}$ even under high temperature and light intensity.
Step 4: Conclusion
Thus, Kranz anatomy is the structural hallmark of plants following the $C_{4}$ photosynthetic pathway. Final Answer: (B)
