The correct Answer is:
To solve the question regarding Selaginella and identify the correct statement, we will evaluate each option provided. ### Step-by-Step Solution: 1. **Evaluate the First Statement:** - The first statement claims that "macrophylls are a characteristic feature of Selaginella." - **Analysis:** Selaginella is known for having microphylls, which are small leaves. Therefore, this statement is incorrect. 2. **Evaluate the Second Statement:** - The second statement states that "the spores germinate to give rise to free-living multicellular thaloid gametophytes." - **Analysis:** This statement is true. In Selaginella, the spores do germinate and develop into free-living multicellular gametophytes, which are thaloid in nature. 3. **Evaluate the Third Statement:** - The third statement mentions that "the sporophytes be a sporangia which produce spores mitotically in the spore mother cells." - **Analysis:** This statement is incorrect because Selaginella produces spores through meiosis, not mitosis. Therefore, this statement is false. 4. **Evaluate the Fourth Statement:** - The fourth statement claims that "it is a homosporous plant meaning it can produce only one type of spores." - **Analysis:** This statement is also incorrect. Selaginella is heterosporous, producing two types of spores: microspores and macrospores. Thus, this statement is false. ### Conclusion: After evaluating all the statements, the only correct statement for Selaginella is the second one: "the spores germinate to give rise to free-living multicellular thaloid gametophytes."
