Tree Trunk Biology and Basic Wood Structure. By. Steve Nix. ... The major structures for water transport in xylem are vessels in angiosperms (hardwoods) and tracheids in gymnosperms (conifers). 4.

In plant xylem tissue, there are two types of cells involved in the actual movement of water, tracheid and vessel elements. For tracheid elements, think of the human trachea, the bony and rigid ...

The stack of dead cells, called xylem vessel members, respond to what’s in the water whipping through, ... He then looked for the structure that carries out this regulation.

“[T]here’s a clear pattern of xylem network shapes starting out with simple forms and becoming more complex,” Brodersen wrote. “Using the arrangement of the conduits within those vessel networks we ...
