🔬 Biology  ·  Photosynthesis in Higher Plants  ·  NEET

C4 plants are efficient in hot, dry climates chiefly because they minimise:

  • A photorespiration
  • B transpiration
  • C normal respiration
  • D seed germination

Correct answer: A. photorespiration

Explanation: The C4 pathway concentrates CO₂ around RuBisCO, suppressing wasteful photorespiration.

Concept context

Light reactions, the Calvin cycle, C3/C4/CAM pathways, photorespiration, and factors affecting the rate of photosynthesis. One of the highest-yield NEET chapters.
