Answer 2

${\bold{\huge{\tt{Solution:-}}}}$

The torus regulates the functions of the bordered pit, and the margo is a cell wall-derived porous membrane that supports the torus. The margo is composed of bundles of microfibrils that radiate from the torus. The margo is flexible and can move towards either side of the pit while under stress.
