Question #46441
The Question
Analyze the following statements regarding the evolutionary and morphological characteristics of Ipomoea batatas (Sweet potato) and Solanum tuberosum (Potato): I. Both structures represent convergent evolution as they are analogous organs performing the similar function of food storage. II. Ipomoea batatas is a modification of a tap root, whereas Solanum tuberosum is a modification of an underground stem. III. The presence of 'eyes' representing axillary buds confirms the morphological consistency of the potato as a stem. IV. Despite their functional similarity, they do not share a common anatomical ancestry. Which of the above statements are CORRECT?

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Integrating evolutionary biology (analogy vs. homology) with precise plant morphology.
The primary trap relies on 'Classification Nuance'—students often remember sweet potato is a root, but fail to distinguish between 'tap root' and 'adventitious root' modifications, which is a high-yield NCERT distinction.
It also tests the ability to link morphological evidence (axillary buds) to evolutionary divergence.
