    Solution:

    The prominent features of dicot stem are:

    1. Demarcation into epidermis, cortex and stele.
    2. Cortex less extensive than stele.
    3. Cortex has continuous or discontinuous few layered collenchymatous hypodermis, parenchymatous inner cortex with intecellular spaces and single layered endodermis that stores starch and known as starch sheath.
    4. Extensive stele having 15-20 top or wedge shaped, conjoint, collateral, open, ectophloic or amphiphloic endarch vascular bundles arranged in the form of a ring (Eustele).
    5. Absence of bundle sheath.
    6. Presence of narrow, radiating medullary rays that connect the medulla with the cortex and help in radial conduction.
    7. Extensive pith.
    8. Absence of lysigenous water cavity in the vascular bundles.
