The correct Answer is:
To analyze the given statements regarding Gymnosperms, Bryophytes, Equisetum, and the reproductive structures in Bryophytes, we will evaluate each statement step by step. ### Step 1: Evaluate Statement A **Statement A:** Gymnosperms are heterosporous. - **Explanation:** Gymnosperms are indeed heterosporous, meaning they produce two types of spores: microspores (male) and megaspores (female). This is a characteristic feature of Gymnosperms. Therefore, this statement is **correct**. ### Step 2: Evaluate Statement B **Statement B:** Bryophytes have well-developed vessels and sieve tubes. - **Explanation:** Bryophytes, which include mosses and liverworts, do not have vascular tissues such as well-developed vessels and sieve tubes. They are considered non-vascular plants. Therefore, this statement is **incorrect**. ### Step 3: Evaluate Statement C **Statement C:** Strobilus is found in the main plant body of Equisetum. - **Explanation:** Equisetum, commonly known as horsetail, is a type of Pteridophyte. It does have a strobilus, which is a reproductive structure that produces spores. The strobilus is found at the top of the fertile shoots. Therefore, this statement is **correct**. ### Step 4: Evaluate Statement D **Statement D:** Antheridia are absent but archegonia are present in bryophytes. - **Explanation:** In Bryophytes, both antheridia (male reproductive organs) and archegonia (female reproductive organs) are present. Therefore, the claim that antheridia are absent is **incorrect**. ### Conclusion After evaluating all statements: - Statement A: Correct - Statement B: Incorrect - Statement C: Correct - Statement D: Incorrect The correct statements are A and C.
