  • c only 2/3 of the CO2 of air
  • d none of the above

Dear Student.
Please find below the solution to the asked query.

The answer is c only 2/3 of the CO2 of air.

Plant consumes CO2 equal to that in 2,500 litres of air in order to synthesise one gram of hexose. The measurement suggests that the plant uses only 2/3rd of the CO2 of the air.
