NEET Biology question
Statement 1: Under conditions of high light intensity and limited carbon dioxide supply, photorespiration has a useful role in protecting plants from photo-oxidative damage. Statement 2: If enough carbon dioxide is not available to utilise light energy for carboxylation, the excess energy may cause damage to the plant.
Answer: (A)
Solution
Photorespiration does act as a protective safety-valve under high light/low CO2 conditions, dissipating excess absorbed light energy that would otherwise cause photo-oxidative damage to the photosynthetic apparatus, so the assertion is a well-established, true statement.
