The vascular bundles of monocots stems typically occurs in a complex three dimensional pattern embedded in a matrix that is called conjunctive tissue. Conjunctive tissue may be either parenchyma as in this corn, or it can consist of fibers whose walls can become extremely thick. Parenchymatous conjunctive tissue occurs in monocot stems that are soft – such as corn, canna lilies, gingers, and bulbs like onions – whereas a fibrous conjunctive tissue occurs in larger, harder monocot stems like bamboo, agaves, and many species of palm trees.

Conjunctive parenchyma is the parenchyma, which occurs in the root system. It is specially meant for storage of water.
