A mutation in a plant affects the development of its palisade parenchyma, significantly reducing the number and length of these cells. Which of the following would be the MOST DIRECT consequence of this mutation on photosynthesis?
Increased rate of photorespiration due to higher oxygen concentration.
Reduced CO2 fixation by RuBisCO in the mesophyll cells.
Decreased light absorption and reduced efficiency of the light-dependent reactions.
Impaired transport of sugars from the source to the sink.
