What structure can the cells of the conducting tissue have?

Any tissue consists of cells united by a common origin, structure and functions performed. But not all cells are the same. Conductive tissue is formed by living or dead cells that look like tubes. Nutrients dissolved in water move along them. There are two groups of conductive tissues: vessels and sieve tubes. Vessels are dead hollow cells connected in series, the transverse partitions between which disappear. Sieve tubes are elongated non-nuclear living cells connected in series with each other. There are fairly large holes in their transverse walls.
