It is an example of a napiform root and a modified taproot.
Taproots are typically straight, thick, and tapering, and they grow directly downward.
Turnips are a root vegetable that belongs to the cruciferous family, along with Brussels sprouts and kale.
They are one of the most important vegetable crops in the world and can be fed to both humans and cattle.
The most commonly used turnips are purple or greenish in color, with a white bulb known as the storage root that grows above ground and has smooth skin free of scars.
Like most cruciferous vegetables, their roots and leaves, also known as turnip greens, are edible.
