Q
Draw the position of the xylem and phloem in the root cross section, Stem cross section and leaf cross section
A
2
Q
Stat how the xylem vessels are adapted for transporting water
A
The cells that make up the xylem are adapted to their function
They lose their end walls so the xylem forms a continuous, hollow tube allowing water and minerals to pass throught eassely
