The arrangement of veins or veinlets on lamina of leaf is known as veination.
Dicots can have many types of veination, including parallel, fan-shaped, and netted. There are several other types of veination that one can find in dicots too.
monocotyledonous
Ivy is a dicot. The easiest way to tell is that the leaves exhibit branched veination, not parallel veination like a monocot would.
Depending on what type of leaf - a monocot leaf (grasses etc) have parallel veination and dicot leaves (woody plants) have reticulate veination (more randomly spread).
Wheat is monocotyledonous, it has a simple leaf with parallel veination
ike most grasses they have simple, alternate leaves with parallel veination
yes
Floral parts in multiples of 3 as well as being tri-locular Fused calyx Strap-like leaves with parallel veination
Advanced features of plants in the division Gnetophyta include vessel elements in their xylem, compound reproductive structures called strobili, and the presence of double fertilization. They also have unique characteristics such as opposite leaves and sometimes vine-like growth habits.
Flower parts of monocot's (petals, anthers etc.) are always in multiples of three i.e. 3, 6, 9 petals. Dicots, floral parts in multiples of 4 or 5. i.e. 4, 8, 12 or 5, 10, 15 Dicots have a separate calyx surrounding the petals, where as monocots have have the calyx fused to the base of the petals. http:/theseedsite.co.uk/monocot.html for more information
