*Chapter 13: PHOTOSYNTHESIS IN HIGHER PLANTS* 🌿   *20 NEET LEVEL QUESTIONS - "NOT ON GOOGLE"* 🔥   _With Detailed Solutions - 1-2Q concepts can come in NEET 2027_ --- ### *SECTION A: CONCEPTUAL + NCERT DEEP* `10Q` *Q1.* In C4 plants, Rubisco is active in bundle sheath cells but not in mesophyll. Reason? A. PEPcase is absent in mesophyll B. O2 concentration is low in bundle sheath = Less photorespiration C. Calvin cycle does not occur in mesophyll D. Bundle sheath chloroplasts are agranal Ans: B + D  Detail: In mesophyll, PEPcase fixes CO2 → OAA → Malate. Malate goes to bundle sheath and releases CO2. In bundle sheath, CO2 high + O2 low = Rubisco carboxylase activity increases, oxygenase decreases. Plus bundle sheath chloroplasts are agranal = Less PS-II = No O2 formed = Photorespiration negligible. This is why productivity is high in Maize, Sugarcane. NEET Trap: Option C is wrong because mesophyll has CO2 fixation even if Calvin is absent. *Q2.* When does cycli...
