Compared to C3 plants, C4 plants ________.
A) can continue to fix CO₂ even at lower CO₂ concentrations and higher oxygen concentrations
B) have higher rates of photorespiration
C) do not use rubisco for carbon fixation
D) make a four-carbon compound, oxaloacetate, which is then delivered to the citric acid cycle in mitochondria

Question

Quizplus · Accepted Answer

C4 plants have a mechanism to concentrate CO₂ in their bundle sheath cells, allowing them to fix CO₂ efficiently even at lower concentrations and higher oxygen levels, reducing photorespiration.
