Give a brief definition of tuberous (storage) root

A tuberous root is a thick, fleshy root that stores water and food (mainly carbohydrates). It acts as an underground storage system, helping the plant survive during tough times like winter or drought.

Key characteristics:

• True root storage: Unlike a potato (which is a stem tuber), a tuberous root is an actual root that swells to store nutrients.
• Irregular shape: Carrots and beets have neat shapes, but tuberous roots don’t follow a pattern—they can look uneven or lumpy.
• Growth buds: New shoots sprout from the top or “crown” of the root, the part once attached to the stem.
• Examples: Sweet potato, cassava, and dahlia are common plants with tuberous roots.
