The xylem is the structure of the plant that is
responsible for transporting water from the ground up to the different parts of
the plant. It is composed water, inorganic ions, and a number of organic chemicals.

Xylem tissue is found throughout the plant
because not only does it transport water, but it also transports the nutrients
that the plant needs for different processes. Aside from being responsible for
the transportation of materials, the xylem is also used to replace water that
was lost during photosynthesis and transpiration. </span>

The reason why compartments exist is to maintain different conditions inside themselves. If there were identical conditions in the various compartments, then they could be one big compartment. For example, lysosomes have specific pH necessary for proper function of enzymes inside them. Mitochondria on the other hand don't need such condititons.
