companion cell A type of cell found within the phloem of flowering plants. Each companion cell is usually closely associated with a sieve element. Its function is uncertain, though it appears to regulate the activity of the adjacent sieve element and to take part in loading and unloading sugar into the sieve element.

Answer:

almost always adjacent to nucleus-containing companion cells, which have been produced as sister cells with the sieve elements

Explanation:

The basic structure of vessels is same as tracheids. The lumen of vessels is wide than tracheids and end wall is perforated (Transverse septum is absent between two vessel elements. If present then porous). Thus vessels are more capable of conduction of water than tracheids.
