Kranz anatomy of C4 plants is
Aa single mesophyll layer
Bmesophyll wraps bundle-sheath cells; fixation is split
Cthin hairless leaves to maximise gas exchange
Dleaves with no chloroplasts in the bundle sheath
Answer & Solution
Correct answer: B. mesophyll wraps bundle-sheath cells; fixation is split
Kranz means 'wreath' in German. C4 leaves have bundle-sheath cells packed in a ring around the vascular bundles, surrounded by mesophyll. Mesophyll does the first CO₂ fix (PEP carboxylase); bundle sheath houses chloroplasts where RuBisCO runs the Calvin cycle at high CO₂.
