Plant morphology: Determine which organ the edible potato (Solanum tuberosum) is a modified outgrowth of. Full question: Potato is a modified form (outgrowth) of which plant organ? Identify the precise botanical classification. Choose the correct option.

Difficulty: Easy

Stem (an underground stem tuber)
Root (a true storage root)
Leaf (a modified foliage organ)
Fruit (a ripened ovary)
Rhizoid (non-vascular anchor)

Correct Answer: Stem (an underground stem tuber)

Explanation:

Given data

Object: Potato tuber.

Concept / Identification
The potato is a stem tuber (underground stem) characterized by nodes and axillary buds (eyes). These features confirm stem origin rather than root (which lacks nodes and axillary buds).

Why others are incorrect
Storage roots (e.g., carrot, beet) are anatomically different; leaves and fruits have distinct tissues; rhizoids occur in non-vascular plants.
