The correct Answer is:
To solve the question of selecting an incorrect statement for gymnosperms, we will analyze the provided statements one by one. ### Step-by-Step Solution: 1. **Understanding Gymnosperms**: - Gymnosperms are a group of seed-producing plants that include conifers, cycads, Ginkgo, and gnetophytes. The term "gymnosperm" means "naked seeds," indicating that their seeds are not enclosed within an ovary. 2. **Analyzing the Statements**: - **Statement 1**: "Some roots of genera will establish symbiotic association with fungus in the form of mycorrhizae." - This statement is correct. Mycorrhizae are indeed symbiotic associations between fungi and plant roots, and many gymnosperms, like Pinus, form such associations. - **Statement 2**: "Leaves can be simple or compound." - This statement is also correct. Gymnosperms can have leaves that are either simple or compound, depending on the species. - **Statement 3**: "Ovules are not enclosed by any integuments." - This statement is misleading. While it is true that gymnosperm ovules are not enclosed by an ovary wall, they are typically surrounded by integuments. Therefore, this statement is incorrect as it implies that there are no integuments at all. - **Statement 4**: "In conifers, leaves reduce the surface area." - This statement is correct. Conifer leaves are often needle-like, which helps to reduce water loss by minimizing the surface area exposed to the environment. 3. **Identifying the Incorrect Statement**: - After analyzing all statements, we find that **Statement 3** is the incorrect statement regarding gymnosperms. It incorrectly states that ovules are not enclosed by any integuments, which is misleading. ### Conclusion: The incorrect statement for gymnosperms is: **"Ovules are not enclosed by any integuments."** ---
