Given

  1. A
    In plants, some binds to RuBisCO, hence fixation is decreased.
  2. B
    In plants, mesophyll cells show very little photorespiration while bundle sheath cells do not show photorespiration.

Solution & Step-by-step Explanation

plants suffer from photorespiration. plants avoid photorespiration altogether because RuBisCO is present in bundle sheath cells where concentration is high, preventing from binding. The reason statement is incorrect as photorespiration is absent in plants (both cell types).
