Kranz anatomy is a characteristic feature of_________?
Correct answer: A. C4 plants
- A. C4 plants
- B. C3 plants
- C. C2 plants
- D. CAM plants
Explanation
Kranz anatomy is characteristic of C4 plants, whose leaves have prominent bundle-sheath cells surrounding the vascular bundles. This arrangement supports the concentration of carbon dioxide around Rubisco. Students may choose CAM plants because they also reduce photorespiration, but CAM plants do not characteristically show Kranz anatomy.

About Cellular Respiration
Cellular respiration releases energy from glucose through glycolysis, the link reaction, the Krebs cycle and the electron transport chain, producing ATP. The pathway differs in oxygen availability: aerobic respiration uses oxygen and yields more ATP, while anaerobic respiration produces much less ATP and forms lactic acid in muscles or ethanol and carbon dioxide in yeast.
