C₄ Plants & Photorespiration Advantage — NEET Biology
📚 Practice ConceptNow that you know that the C₄ plants lack photorespiration, you probably can understand why productivity and yields are better in these plants. In addition, these plants show tolerance to higher temperatures.
Match the following characteristics of C₄ plants with their associated mechanisms and physiological advantages: Column I (C₄ Characteristic) A. Kranz Anatomy B. PEPcase activity C. CO₂ transport to bundle sheath D. RuBisCO location in bundle sheath Column II (Mechanism/Enzyme) I. High CO₂ affinity II. Thick-walled bundle sheath cells III. C₄ acids decarboxylation in bundle sheath DIV. Spatial separation of reactions Column III (Physiological Advantage) 1. Increased CO₂ fixation at low atmospheric CO₂ 2. Minimised oxygenase activity of RuBisCO 3. Tolerance to higher temperatures and light intensities 4. Greater productivity and biomass production Which of the following options provides the correct set of matches?
