Explanation:

Minute openings (pits) in the secondary cell wall of water conducting elements play an important role in water transport in living plants.

They allow the flow of water and nutrients from one element to another, linking water uptake in roots with transpiration in leaves.

The functionality of the xylem network depends to a large degree on bordered pits that connect adjacent conduits and the finely porous pit membranes, which prevent the movement of gas and pathogens between conduits (Zimmermann & Brown, 1971).

Thus bordered pits act as safety valves in the hydraulic system of plants.
