AP BIOLOGY

Detailed explanation-1: -Vegetables are usually grouped according to the portion of the plant that is eaten such as leaves (lettuce), stem (celery), roots (carrot), tubers (potato), bulbs (onion) and flowers (broccoli).

Detailed explanation-2: -Tubers are usually high in starch. Examples are kūmara, potatoes, (storage root), yam, taro, Jerusalem artichoke and ulluco.

Detailed explanation-3: -Common examples edible of tubers include potatoes, jicama, sunchokes, and yams. Root tubers (like sweet potatoes or cassava) are often mistakenly classified within this category, but because they have swollen roots (rather than stems) they don’t fit the technical bill for what a true tuber is.
