The correct Answer is:
To solve the question of identifying the incorrect statement about the anatomy of angiosperms, we will analyze each of the provided statements one by one. ### Step-by-Step Solution: 1. **Statement 1**: "The cells of medullary rays adjoining the intrafascicular cambium become meristematic and form intrafascicular cambium." - **Analysis**: This statement is correct. The medullary rays in the vascular tissue can become meristematic and contribute to the formation of the intrafascicular cambium. 2. **Statement 2**: "In isobilateral leaves, mesophyll is undifferentiated into palisade and spongy parenchyma." - **Analysis**: This statement is also correct. Isobilateral leaves, which are typically found in monocots, have a mesophyll that does not differentiate into distinct palisade and spongy layers. 3. **Statement 3**: "Vascular bundles in dicot stems are arranged in a scattered manner." - **Analysis**: This statement is incorrect. In dicot stems, vascular bundles are arranged in a ring or a circular pattern, not scattered. This arrangement is characteristic of dicots, while monocots have scattered vascular bundles. 4. **Statement 4**: "Boliform cells are observed in leaves of some monocots." - **Analysis**: This statement is correct. Boliform cells, which are specialized parenchyma cells, can indeed be found in the leaves of certain monocots. ### Conclusion: After analyzing all four statements, the incorrect statement is **Statement 3**: "Vascular bundles in dicot stems are arranged in a scattered manner." ### Final Answer: The incorrect statement is **Statement 3**. ---
