Mark every accurate description of the vessels that make up xylem. Select all that apply.

Erklärung

A xylem vessel is a file of cells that die and lose their contents, which leaves an open pipe that water can move along without crossing anything living. The idea that a transport tissue must be alive, or that a living neighbour keeps each vessel topped up with cytoplasm, fails on the same point: contents of any kind would obstruct the water column, and it is the sugar-carrying tissue that stays alive to do its very different job.
