| Monocot Stem | Dicot Stem |
| The plants whose seed contains only one embryonic leaf are called monocots. | The plants whose seed contains two cotyledons or embryonic leaves are called dicots. |
| Ground tissues are not differentiated into cortex and pith. And composed of parenchyma. | Cortex is present. It is composed of collenchyma and parenchyma. |
| The endodermis is absent. | Endodermis is present. |
| Vascular bundles are scattered irregularly. | Vascular bundles are arranged in rings. |
| The vascular bundles are smaller towards the periphery and larger towards the center. | In these, vascular bundles have a uniform size. |
| In monocot stems, vascular bundles are closed. | In dicots stems, vascular bundles are open. |
| Cambium is absent in monocots. | Dicots have cambium between the xylem and phloem. |
| There is no hard bast. | Pericycle forms sclerenchyma or hard bast outside the vascular bundles. |
| The xylem is V-shaped. There are four distinct vessels. | The xylem vessels are arranged in radial rows. |
| Phloem parenchyma is absent. | Phloem parenchyma is present. |
| Lysogenous cavity may be present in the protoxylem. | Lysogenous cavity is not present in the protoxylem. |
| Each vascular bundle is closed in a sclerenchymatous sheath. | Vascular bundles are not closed in the sclerenchymatous sheath. |
| Medullary rays are absent. | Dicots have medullary rays present in between the xylem and phloem. |
| They lack secondary growth. | Secondary growth occurs. |
