Plant Anatomy

ANATOMY OF DICOTYLEDONOUS AND MONOCOTYLEDONOUS PLANTS

Dicotyledonous Root

Epidermis: The epidermis forms the outermost layer. Unicellular root hairs are present. The cortex is composed of many layers of thin-walled parenchyma; with intercellular spaces. The innermost layer of the cortex is called endodermis.

Endodermis: This is composed of a single layer of barrel-shaped cells. Intercellular space is absent. The tangential as well as radial walls of endodermis have a deposition of water-impermeable, waxy material; called suberin; in the form of casparian strips. A few layers of thick-walled parenchymatous cells lie next to the endodermis. This is called pericycle. The cells of the pericycle initiate lateral roots and vascular cambium during secondary growth. The pith is small and inconspicuous
