B In C4 cells, CO2 is fixed at night to decrease water loss.C C3 plants deliver CO2 to the Calvin cycle using bundle sheath cells sheltered from leaf air spaces. D In C3 plants, O2 competes with CO2 for the active site of RuBP carboxylase. E C3 plants have chloroplasts in the both the bundle sheath cells and the mesophyll cells.

Answer 1
