The correct Answer is:
To analyze the given assertion and reason, we can break down the information step by step. ### Step 1: Understanding the Assertion - **Assertion**: Spores in mosses are contained within the capsule. - **Explanation**: In mosses, the sporophyte generation produces a structure called the capsule, which is where the spores are formed and stored. This statement is true. ### Step 2: Understanding the Reason - **Reason**: Spores are formed by mitotic division in mosses. - **Explanation**: Spores in mosses are actually produced through meiotic division, not mitotic division. The process of meiosis results in haploid spores (N), which is characteristic of the moss life cycle. Therefore, this statement is false. ### Step 3: Conclusion - Since the assertion is true and the reason is false, the correct conclusion is that the assertion is correct, but the reason provided is incorrect. ### Final Answer - The assertion is true, and the reason is false. ---
