The correct Answer is:
To solve the assertion and reason question, we will analyze both statements step by step. ### Step 1: Analyze the Assertion - **Assertion**: "Cytokinins increase the shelf life of fruits and vegetables." - **Evaluation**: This statement is true. Cytokinins are a class of plant hormones that play a significant role in promoting cell division and delaying senescence (aging) in plants. By delaying senescence, cytokinins help maintain the freshness and quality of fruits and vegetables, thus increasing their shelf life. ### Step 2: Analyze the Reason - **Reason**: "Cytokinins induce cell division." - **Evaluation**: This statement is also true. Cytokinins are known to promote cell division in plant tissues. They work in conjunction with other hormones, such as auxins, to stimulate cell growth and division, which is crucial for plant development. ### Step 3: Determine the Relationship - While both the assertion and the reason are true, we need to determine if the reason provided is the correct explanation for the assertion. - The assertion states that cytokinins increase shelf life, while the reason states that they induce cell division. While inducing cell division is one of the functions of cytokinins, it does not directly explain how they increase the shelf life of fruits and vegetables. The increase in shelf life is primarily due to the prevention of senescence and degradation of chlorophyll, not just cell division. ### Conclusion - Both the assertion and reason are true, but the reason does not adequately explain the assertion. Therefore, the correct answer is that both statements are true, but the reason is not the correct explanation for the assertion. ### Final Answer - Both assertion and reason are true, but the reason is not the correct explanation for the assertion. ---
