| Stem | Root |
| mostly epidermis is covered by distinct cuticle. | Epiblema lacks cuticle. |
| Stem hairs are either unicellular or multi cellular they are separated from epidermal cells by walls. | Root hairs are unicellular. |
| Stomata may occur in epidermis. | They are not separated from cells of epiblema by w alls. |
| cortex is generally differentiated into zones like hypodermis, general cortex and endodermis. | Stomata are absent. |
| Hypodermis is either collenchvmatous or selerenchymatous. | Cortex is an undifferentiated mass. |
| Endodermis lacks casparian strips; cells of endodermis contain starch grains. | Hypodermis is absent |
| Pericycle is not present in all stems. | Thick walled exodermises is present in some roots in its place |
| Lateral branches are superficial. | Endodermis is distinct with casparian strips, pericycle is present. |
| They do not develop from pericycle. | Lateral roots arise from pericycle. |
| Vascular bundles are conjoint, collateral or concentric. | Vascular bundles are radial in arrangement. |
| Xylem is endarch. | Xylem is exarch. |
