The right answer is tracheids allow for efficient transport of water over longer distances.
Tracheids are conduits for the transport of raw sap (composed of water and mineral salts) to vascular plants. They are composed of a series of elongated cells. During the formation of tracheids these cells die, are emptied of their contents and are fused vertically to form a hollow conduit. The tracheids are located in the xylem, plant tissue allowing the transport of raw sap. Derived from the primary xylem (protoxylème), they have a role in the overall support of the plant.
In addition to tracheids, angiosperms possess vessel elements for transporting raw sap.
Non carbohydrates refers to those food which are not carbohydrates, which means that, these food do not supply energy and one can not possibly grow fat by eating them too much. Examples of non carbohydrate foods are egg, meat, fish, poultry, etc.
Non carbohydrates foods usually play other roles in the human system other than providing energy.
