Full Answer

Monocots are marked by a single cotyledon that is contained inside their seed coat. When a monocot begins to grow, the seed leaf produces a single leaf on the new plant. A monocot leaf is long, narrow and contains veins that run up and down the length of the leaf. Its roots are unbranched and fairly fragile.

Dicots produce two leaves when they first germinate. The leaves of a dicot vary in shape and size, with the veins extending out from the center to form. Roots of a dicot are tough and branched.

    What is the difference between monocot and dicot flowers?

    A:

    According to the University of California Museum of Paleontology, the major morphological differences between monocot and dicot flowers include the number of cotyledons, pollen structure, number of flower parts, leaf veins, stem vascular arrangement, root development and secondary growth. The actual basis for differentiating the two classes of angiosperms is the number of cotyledons in the embryo.
