The root endodermis is made up of some suberin containing cells that are arranged in the form of strips, called the Casparian strips. These cells are present in the roots of both monocots and dicots. The suberin in the Casparian strip forms an impermeable layer that only allows the transport of certain ions and water.

Features Features The presence of a single cotyledon in the seedling is the most common way to identify monocot plants. Veins that run parallel to the length of the leaves and flower sections that are arranged in a three or six-fold symmetry are some of the anatomical characteristics shared by monocots. Monocots have very little true woody tissue and an adventitious root system. They lack a typical cambium and have scattered vascular bundles.
