Full Answer

Monocot stems differ from those of dicots in regards to the organization of the vascular bundles within the plant stem. In monocots, the vascular bundles are situated sporadically inside the stem. However in dicots, the vascular bundles are organized in more of a donut pattern.

In addition to the differences in stems, monocot and dicot plants also have comparable characteristics in their root structures, leaves, and seeds. Monocot roots tend to spread out in many different directions in order to populate the surface soil. However, dicot roots tend to grow downward and are normally situated around a centralized taproot, from which other smaller roots branch off from.

There is also a difference between the two in terms of the arrangement of the veins within the leaves of the respective plants. In monocot leaves, the veins are aligned parallel to one another, whereas in dicot leaves the veins are situated in a more branching pattern.

In regards to the differences in seeds between the two, monocot seeds have a single cotyledon vein compared to the dicot seed which has two.
