Question

Assertion :Higher yields in case of bell pepper can be achieved by growing them in carbon dioxide enriched green houses. Reason: In the case of bell pepper, due to higher intracellular CO${}_2$ concentration in bundle sheath cells RuBisCo mainly acts as carboxylating enzyme.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
• C. Assertion is correct but Reason is incorrect.
• D. Both Assertion and Reason are incorrect.

Answer 1

The correct option is C Assertion is correct but Reason is incorrect.

Many vegetables are cultivated in green houses throughout the world. The vegetables which give high yield are cultivated in green houses where the growth conditions can be maintained. Capsicum or bell pepper are grown in green houses where they are enriched with higher concentration of carbon dioxide. In closed environment with high levels of carbon dioxide, there is net increase in the rate of photosynthesis and yield. Bell peppers are the C3 plants and do not have differentiated bundle sheath and mesophyll cells.

So, the assertion is correct but the reason is incorrect.

Thus, the correct answer is option C.
