Root vegetables are underground plant parts eaten by humans as food. Both root vegetable and tubers are geophytes, a botanical classification for plants with their growing point beneath the soil. All tubers fall under the root vegetable umbrella, but not all root vegetables are tubers. 1) Root vegetables are aptly named because the meat of the crop is the root of the plant, growing downwards and absorbing moisture and nutrients from the soil. Above ground you’ve got the green stuff, below ground, you’ve got the root. 2) Tubers, however, form at the base of the root, store energy and support new stem growth. When it comes to tubers, you got the green stuff above ground, and then below ground you have a system of hairy like roots - from that the tubers will grow. You can get several tubers from one above-ground plant, while root crops will have one root vegetable from each plant.
