Read the following statements and choose the following option: 1. Photorespiration does not occur in C4 plants 2. RuBisCO functions as a carboxylase minimising the oxygenase activity in C4 plants 3. The C3 and C4 plants respond same to CO2 concentrations. 4. The C4 plants show saturation at about 450 μlL-1

Options

  1. ABoth 2 and 4 are incorect
  2. BBoth 1 and 2 is correct
  3. COnly 2 is correct
  4. DOnly 3 is correct

Correct answer

B. Both 1 and 2 is correct

Step-by-step solution

In C4 plants photorespiration does not occur. This is because they have a mechanism that increases the concentration of CO2 at the enzyme site.
