  More on Morphology of the Monocots
The vascular strands in monocots are not arranged in a neat ring, as they are in dicots, but are scattered within the stem.
This refers to the arrangement of vascular strands in the stem, which in the case of monocots are scattered in the stem, though more densely packed near the periphery of the stem.
In the monocots, palms, grass-trees, bamboo, pandanes, and yuccas are among the groups which grow as trees.

  NationMaster - Encyclopedia: Monocot
The monocots are considered to form a monophyletic group which evolved from an early dicot.
The earliest fossils presumed to be monocot remains date from the early Cretaceous period.
In monocot stems, the vascular tissues — the phloem and xylem — are in bundles scattered throughout the stem, and they typically lack a vascular cambium.

 Monocot and Dicot Seeds - Picture - MSN Encarta
Monocotyledons (monocots) and dicotyledons (dicots) make up the two large groups of flowering plants, differentiated by their seed structures.
Monocot seeds contain one cotyledon, or embryonic leaf.
For a brief time, the cotyledons also serve as the first photosynthesizing leaves, but they wither and die when the true leaves emerge.

 Monocots & Dicots
The veins in monocot leaves are usually but not always aligned parallel with one another, as in blades of grass.
Cut across a monocot's stem and the water-bearing tubes, or vascular bundles, inside are scattered throughout the pith, not arranged in concentric rings like the rings of a tree.
When a monocot's seed sprouts, the first leaf up is a single spike looking like a simple blade of grass arising from the soil.

 Brooklyn Botanic Garden: Plant Family Collection: Monocots
Monocots have one cotyledon (the first leaf produced on a seedling).
Botanists believe that monocots evolved from dicots by reduction—that is to say, by losing one of the two seed leaves found in every dicot.
In the Plant Family Collection, the monocots are represented in the Monocot Border, overflowing with grasses, lilies, cannas, a banana tree, and other spectacular specimens.

 Monocots vs. Dicots
Leaf veins -- In monocots, there are usually a number of major leaf veins which run parallel the length of the leaf; in dicots, there are usually numerous auxillary veins which reticulate between the major ones.
This arrangement is unique to monocots and some of their closest relatives among the dicots.
By contrast, the radicle aborts in monocots, and new roots arise adventitiously from nodes in the stem.

The vascular tissue in monocots are scattered; however, in dicots the vascular tissues are in a circle.
Monocots have a lot of characteristics that you can see just by looking at the flower but others such as the one seed leaf or the scattered bundles of veins you can’t see just by looking.

 Monocot Seed   (Site not responding. Last check: )
In corn and other monocots, the single cotyledon, known as the scutellum, absorbs food reserves from the endosperm.
The coleoptile and coleorhiza are sheaths that enclose the apical meristem of the shoot and root respectively.
The monocot cotyledon -- scutellum is used for food storage and digestion.

Monocots have "Parallel" or Striate venation which is characterized by veins which run parallel to one another over a large expanse of the Blade (Lamina).
Monocots usually do not have a midrib and the blade is more uniform in its thickness.
Because the large veins in monocot leaves lie parallel to one another, they are cut at a 90 degree angle in a cross section.

 BANGLAPEDIA: Monocot Plant
Phylogenetically, the monocots are now believed to have been derived from very primitive stock of Ranalian ancestry, and hence they are considered phylogenetically advanced than the dicots.
Most monocots are herbaceous, only Arecaceae have some trees (Palmyra palm, Fishtail palm, Royal palm, Coconut palm, Date palm, etc) but usually they are unbranched, and unlike dicot trees, have leaves making a crown at the top.
Monocot plants have vascular bundles in stem, which are closed and scattered in the ground tissue.

 Re: Can a plant be both monocot and dicot?
Monocots and dicots are generally distinguished from each other by several characteristics, including cotyledon number, root system type, leaf venation, numbers of flower parts, and vascular bundle arrangement in the stem.
However, sometimes a particular monocot species may have some characteristics like a dicot and a particular dicot species may have some characteristics like a monocot.
For example, one exception to the rule that dicots have two cotyledons and monocots have one cotyledon is the dicot water lily (genus Nymphaea) which has what appears to be one cotyledon with two lobes, but which is usually considered to be two cotyledons that have fused.

 General Monocot Transformation Methods
Japan Tobacco claims the transformation of a monocot callus during a dedifferentiation process and the transformation of the scutellum of an immature embryo prior to dedifferentiation.
In the United States, the breadth of the claimed monocot callus transformation is limited only by the minimum number of days in culture before the transformation process takes place.
The invention is thus limited to transformation of a monocot inflorescence.

A traveling exhibit on monocot phylogeny and evolution will be displayed in New York City, Chicago, and San Francisco; computer graphics associated with this exhibit will be distributed to all institutions involved in the study.
Posters illustrating monocot diversity, phylogeny, and evolution will be designed and made available on CD for local printing and web viewing in classrooms around the country.
