Common Distinctiveness of the Inner Formation of Monocot Root
The internal structure of monocot stems differs in some respects from that of dicots. The most important feature of monocot stem is the occurrence of scattered vascular bundles and absence of distinction between cortex and pith. A transverse section of a monocot stem will show only two distinct regions namely epidermis and ground tissue.
Features of a Monocot Root
- Presence of a distinct pith.
- Presence of passage cells and casparian thickenings in the endodermis.
- Presence of thin walled cells in the epiblema.
- Presence of parenchyma cells in the pericycle.
- Absence of cuticle and stomata.
- Presence of unicellular root hairs.
- Presence of radial vascular bundles with polyarch condition and an exarch xylem.
