A Vessel Element Would Likely Lose Its Protoplast in Which

Question

A vessel element would likely lose its protoplast in which section of a root?
A)zone of cell division
B)zone of elongation
C)zone of maturation
D)root cap
E)apical meristem

Accepted Answer

The zone of maturation is where cells differentiate and lignify, meaning they become hardened and specialized for their functions. Vessel elements are specialized cells in xylem tissue that conduct water, but they no longer have a protoplast (living contents) at maturity. Therefore, it is in the zone of maturation where they would lose their protoplast.
