Carrot

The carrot (Daucus carota subsp. sativus, Etymology: Middle French carotte, from Late Latin carōta, from Greek καρότον karōton, originally from the Indo-European root ker- (horn), due to its horn-like shape) is a root vegetable, usually orange in colour, though purple, red, white, and yellow varieties exist. It has a crisp texture when fresh. The most commonly eaten part of a carrot is a taproot, although the greens are edible as well. It is a domesticated form of the wild carrot Daucus carota, native to Europe and southwestern Asia. The domestic carrot has been selectively bred for its greatly enlarged and more palatable, less woody-textured edible taproot.
