Distinctiveness of the inner organization of Dicot Root
- Epiblema is the outermost unilayered with several unicellular root hairs. It consists of thin walled, compactly arranged living parenchymatous cells.
- Cuticle is absent in the epiblema and well fitted with unicellular root hairs.
- Cortex is thin walled, multilayered region made from circular or polygonal parenchymatous cells.
- Endodermis is the innermost layer of cortex and covers the stele. It consists of one layered cells and casparian strips are present in endodermal cells.
- Pericycle is the outermost layer of stele and composed of uniseriate layer of parenchymatous cells. It is composed of one Layered cells.
- Vascular bundles are two or six in number and they are radial type.
- Xylem is exarch type, i.e., proto-xylem is situated towards the periphery.
