Its growth occurs via the loosening of the microfibrils, pectins, and other polymers, as regulated by expansins and caused by acidic conditions stimulated by auxin.
Multinet growth only occurs in this structure's outer layers, but the microfibrils that primarily compose it are laid mostly transverse to its direction of growth.

The interconnection of these structures is the apoplast.  It is very thin for parenchyma and growing cells, while its lignified secondary type makes up much of xylem tissue. There are usually primary and secondary instances of this structure. For 10 points, name this outer layer made mostly of cellulose, that provides structural support to a plant cell.
