Principle

The stem of plants must accomplish various functions. It
supports the leaves, the lateral branches, and the blossoms. The
mechanical supportive tissue (collenchyma) is responsible for the
necessary stability and elasticity. Did you ever come to think
about how a 20m-tall tree is capable of transporting water all the
way from its roots to its crown? Or how it may be possible that
assimilates from the leaves ever arrive at the roots? We want to
explore this pathway of transportation, for which all plants
possess a one-way traffic system. The vascular bundles contain
vessels for transporting water from the bottom up, and sieve tubes
for transporting assimilates from the top down to the bottom. The
structural arrangement of the vascular bundles in the
dicotyledonous plants differs distinctly from the arrangement found
in the monocotyledonous plants.
