Given below are two statements: Statement I: The primary CO 2 acceptor in C 4 plants is phosphoenolpyruvate and is found in the mesophyll cells. Statement II : Mesophyll cells of C 4 plants lack RuBisCo enzyme. In the light of the above statements, choose the correct answer from the options given below :

Options

  1. ABoth Statement I and Statement II are incorrect
  2. BStatement I is correct but Statement II is incorrect
  3. CStatement I is incorrect but Statement II is correct
  4. DBoth Statement I and Statement II are correct

Correct answer

D. Both Statement I and Statement II are correct

Step-by-step solution

Phosphoenolpyruvate or PEP is the 3C compound and acts as the primary carbon dioxide acceptor in the mesophyll cells of C 4 plants, leading to the formation of OAA, C 4 acid. Ribulose-1,5-bisphosphate carboxylase oxygenase (RuBisCO) is an enzyme found in the mesophyll cells present within the C 3 plants. In C 4 plants, this enzyme is found in the bundle sheath cells.
