Which specialized anatomical feature characterizes the leaves of C4 plants?
Answer and explanation
Correct answer: D. Kranz anatomy
- Step 1: C4 plant leaves possess distinct wreath-like concentric rings of large bundle sheath cells surrounding vascular bundles. Step 2. This microscopic arrangement is known as Kranz anatomy (from German 'Kranz' meaning wreath). Answer: Kranz anatomy. Why not the others: Dorsiventral is standard dicot C3 leaf anatomy; isobilateral is standard monocot C3 leaf anatomy; velamen is spongy aerial root tissue in orchids.
