The correct Answer is:
To solve the question, we need to analyze each pair of plants and their respective structures to determine which one is incorrectly matched. ### Step 1: Analyze the first pair - Rhizophora and Pneumatophores - **Rhizophora** is a genus of mangrove trees that grow in swampy areas. - **Pneumatophores** are specialized aerial roots that help the plant in gas exchange, particularly in oxygen-poor environments. - **Conclusion**: This pair is correctly matched. **Hint**: Pneumatophores are adaptations for breathing in waterlogged soils. ### Step 2: Analyze the second pair - Ficus benghalensis and Stilt Roots - **Ficus benghalensis**, commonly known as the banyan tree, has roots that grow downwards from its branches. - These roots are known as **stilt roots** or **prop roots**, which provide additional support to the tree. - **Conclusion**: This pair is correctly matched. **Hint**: Look for the structural adaptations that provide support to large trees. ### Step 3: Analyze the third pair - Bryophyllum and Leaf Buds - **Bryophyllum** is known for its ability to reproduce vegetatively through its leaf buds. - These leaf buds can develop into new plants when they fall off the parent plant. - **Conclusion**: This pair is correctly matched. **Hint**: Bryophyllum is famous for its unique method of vegetative propagation. ### Step 4: Analyze the fourth pair - Pumpkin and Tendrils - **Pumpkin** plants have **tendrils**, which are modified stems that help the plant climb and support itself. - Tendrils are indeed a characteristic feature of many climbing plants, including pumpkins. - **Conclusion**: This pair is correctly matched. **Hint**: Tendrils are important for climbing plants to secure themselves. ### Final Conclusion After analyzing all four pairs, we find that all pairs are correctly matched except for the second pair, where the term "stilt roots" is not the most accurate description for the roots of Ficus benghalensis. The correct term should be "prop roots". Thus, the answer to the question is: **(b) Ficus benghalensis - stilt roots** is the exception.
