In young roots water enters directly into xylem vessels and
tracheids why?

Dear Student,
In young roots, water enters directly into the xylem vessels and
tracheids since these are non living conduits and they are part of
the apoplast The mechanism is based on purely physical forces
because the xylem and tracheids are lifeless Hence, roots are not
needed
