Given below are two statements:Statement I: The primary CO2 acceptor i...
The correct answer is option 'D': Both Statement I and Statement II are correct.
Explanation:
C4 plants are a unique group of plants that have evolved a specialized mechanism to overcome the limitation of photorespiration and enhance their photosynthetic efficiency in hot and dry conditions. The key features of C4 plants include the presence of two distinct types of photosynthetic cells - mesophyll cells and bundle sheath cells.
Statement I: The primary CO2 acceptor in C4 plants is phosphoenolpyruvate (PEP) and is found in the mesophyll cells.
- In C4 plants, the initial fixation of CO2 occurs in the mesophyll cells, where a molecule called phosphoenolpyruvate (PEP) acts as the primary CO2 acceptor. PEP carboxylase enzyme catalyzes the reaction between CO2 and PEP to form a four-carbon compound called oxaloacetate (OAA). This process is known as C4 carbon fixation.
Statement II: Mesophyll cells of C4 plants lack RuBisCo enzyme.
- This statement is incorrect. While it is true that mesophyll cells of C4 plants do not contain a high concentration of RuBisCo (the enzyme responsible for the initial fixation of CO2 in C3 plants), they do contain a small amount of RuBisCo. The low concentration of RuBisCo in mesophyll cells helps to prevent photorespiration and allows the plants to efficiently fix CO2 through the C4 pathway. However, the primary function of RuBisCo in C4 plants is to catalyze the regeneration of the CO2 acceptor molecule in the bundle sheath cells, where the Calvin cycle takes place.
Conclusion:
In conclusion, both Statement I and Statement II are correct. The primary CO2 acceptor in C4 plants is phosphoenolpyruvate (PEP) found in the mesophyll cells, and although mesophyll cells of C4 plants have a low concentration of RuBisCo, they do contain a small amount of this enzyme.

In C4 plants, the primary CO2 acceptor is indeed phosphoenolpyruvate (PEP), which is found in the mesophyll cells. These cells are responsible for the initial fixation of CO2 in the C4 pathway. The C4 plants have evolved this mechanism to minimize photorespiration and increase photosynthetic efficiency under high light intensities and high temperatures.
Statement II is also correct because mesophyll cells in C4 plants lack the RuBisCo enzyme. Instead, the RuBisCo enzyme is located in the bundle sheath cells, where CO2 is concentrated and fixed again through the Calvin cycle. This spatial separation of CO2 fixation enables C4 plants to maintain high rates of photosynthesis and avoid photorespiration.
