Question

RUBISCO enzyme is absent in mesophyll cells in $C_4$plants, but present mesophyll cells of $C_3$ plants.

• A. True
• B. False

Answer 1

The correct option is A True

Ribulose-1,5-bisphosphate carboxylase (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. RUBISCO plays a vital role in carbon fixation during the Calvin cycle. Hence, the statement given is 'True'.
