The correct Answer is:
To solve the question regarding the assertion and reason related to Cnidoblasts in Cnidarians, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "Cnidoblasts are present on the tentacles and the body in cnidarians." - Cnidoblasts, also known as cnidocytes, are specialized cells found in Cnidarians (like jellyfish, corals, and sea anemones) that contain stinging organelles called nematocysts. 2. **Evaluating the Assertion**: - This statement is true because cnidoblasts are indeed located on the tentacles and body of cnidarians, serving as a key feature of their anatomy. 3. **Understanding the Reason**: - The reason states that "Cnidoblasts are used for anchorage, defense, and capture of the prey." - Cnidoblasts play a crucial role in the survival of cnidarians by allowing them to anchor themselves, defend against predators, and capture prey. 4. **Evaluating the Reason**: - This statement is also true. Cnidoblasts are essential for these functions, which are vital for the cnidarian's survival and feeding. 5. **Analyzing the Relationship**: - While both the assertion and reason are true, we need to determine if the reason provides a correct explanation for the assertion. - The assertion discusses the presence of cnidoblasts, while the reason discusses their functions. The reason does not explain why cnidoblasts are found in those locations (tentacles and body). 6. **Conclusion**: - Therefore, both the assertion and reason are true, but the reason does not correctly explain the assertion. The correct conclusion is that both statements are true, but the reason is not the correct explanation of the assertion. ### Final Answer: Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
