Dicot plants differ in structures of their seeds, foliage, and flowers, from the monocotyledons. They can be easily distinguished by studying their distinct characteristics.
Seed The most important difference between the monocots and dicots is the number of embryonic leaves or cotyledons. There are two cotyledons in the seeds of these plants that actually emerge above the soil when the seed germinates. They then turn green and form the first two leaves of the new plant. Leaves The leaves of the dicot plants have veins that form a branched pattern, unlike monocots, in which they run parallel. The veins are actually netted or webbed on the whole surface of the leaf. Vascular Structure In dicots, the stems have vascular bundles, consisting of two structures, the xylem, and the phloem. The xylem helps to transport water and minerals from the root to the other parts of the plant and the phloem transports food that is made in the leaves, to the storage organs. These vascular bundles are arranged in a circular manner around the edge of the stem. Flowers The flower parts are Dicot usually present in fours or fives. Sometimes, they are found in multiples of either number. These flower parts include petals, sepals, and pistils, and the reproductive parts of the plant. Roots Roots in dicots are often fibrous and branched. They branch out into many smaller parts that form a dense network of the root system, unlike monocot plants, that have a tap root system.
