Multiple Choice
The potato (Solanum tuberosum) and the sweet potato (Ipomoea batatas) are both plants that form starchy tubers. A tuber is an underground part of plant used for nutrient storage and is the part of the potato and sweet potato that we eat. Most other plants of both the genus Solanum, which includes the tomato and the eggplant, and the genus Ipomoea, which includes the morning glory, do not form tubers. As described do you think the tubers found in potatoes and sweet potatoes are more likely an example of analogy or homology and why?
