Question

Assertion :Sugar beet, cabbage, carrot like plants are monocarpic. Reason: Both vernalization and photoperiodism, are related to flowering.

• 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 A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Those plants that flower only once in their lifetime are called monocarpic plants. Those monocarpic plants that normally flower and die in the second season are biennial monocarpic plants. For example, cabbages, carrots, sugar beet etc. Photoperiodism is the response of the plant to the relative length of the dark and light period. The flowering depends on the length of day and light period in a plant. The cold treatment given to the buds or seedlings to promote the early flowering is called vernalization. Both of these are related to flowering.

So, the correct option is A.
