A doctor will determine the underlying cause of dry mouth in the patient and then take steps to minimize the underlying cause, such as stopping a medication causing the dry mouth. For many individuals, however, little can be done to alter the underlying cause.
The carrot (Daucus carota subsp. sativus) 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 sometimes eaten 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.
A carrot is a good example of a taproot system, the root dives straight down into the soil. Fibrous systems form a wide, shallow mat of fine roots not too far from the surface of the soil -- grass is an example.Adventitious roots are those that develop wherever part of a plant touches soil and can help plants cling, climb and spread, as ivy does. Many plants have a combination of these systems. carrot is a good example of a taproot system, the root dives straight down into the soil.
