← Nature & AnimalsWhich consequence results when stomata remain persistently closed in C3 rice plants?
A)Photorespiration rates increase severely✓
B)Enhanced nitrate assimilation occurs
C)Turgor pressure increases excessively
D)Non-photochemical quenching decreases drastically
💡 Explanation
Photorespiration increases because persistent closure of stomata prevents CO2 entry, favoring O2 binding by RuBisCO. Therefore, photorespiration increases greatly, rather than turgor pressure increases or non-photochemical quenching decreases, because the plant primarily is undergoing self-defeating carbon fixation.
