Eudicot roots lack xylem and phloem, whereas monocot roots have both xylem and phloem. c. In eudicots, the xylem and phloem are at the periphery, whereas in monocots, the xylem and phloem are located near the center of the root. Dicot stems have their vascular bundles in a ring arrangement. Monocot stems have most of their vascular bundles near the outside edge of the stem. Monocot roots, interestingly, have their vascular bundles arranged in a ring. Dicot roots have their xylem in the center of the root and phloem outside the xylem. Monocot roots lack xylem and phloem, whereas eudicot roots have them arranged at the periphery of the root. Feedback The correct answer is: In monocots, the xylem and phloem are at the periphery, whereas in eudicots, the xylem and phloem are located near the center of the root. The main difference between monocots and Eudicots is found in their seed structure. Specifically, when the seed germinates, the monocot will form one seed leaf (the cotyledon) and the Eudicot will form two seed leaves. The monocot will send up one shoot, while the eudicot sends up one shoot that splits into two parts. Most dicots, however, share a common pollen structure that differs from that of monocots and a minority of dicots; this large subgroup of dicots is called eudicots. A plant's pollen structure is what makes it a eudicot, but its seeds differ from those of monocots in the same way that the seeds of all dicots differ.

The dicots have leaves with a network of veins while monocots have leaves with parallel veins. The xylem and phloem in a dicot are arranged in a ring while they are randomly arranged in a monocot. The monocot seed has one seed leaf while the dicot has two seed leaves.

Monocots have a root system that is composed of a network of fibrous roots as shown in the picture to the right. These roots all arose from the stem of the plant and are called adventitious roots. Also, woody trees that are not gymnosperms (pine, cedar, cypress, etc. ) are dicots.

Grass is a monocot. It exhibits all the characteristics of the monocots. Based on the number of cotyledons present in the seed, all flowering plants are classified into monocots and dicots. Monocots are called as monocotyledonous plants and dicots are called as dicotyledonous plants.

Legumes (pea, beans, lentils, peanuts) daisies, mint, lettuce, tomato and oak are examples of dicots. Grains, (wheat, corn, rice, millet) lilies, daffodils, sugarcane, banana, palm, ginger, onions, bamboo, sugar, cone, palm tree, banana tree, and grass are examples of plants that are monocots.

Characteristics of Dicot Stem Typical dicot stem show following characteristics: Presence of well-defined epidermis with cuticle and multicellular stem hairs. Cortex has collenchymatous hypodermis regularly or as discontinuous patches. Endodermis is distinct as the innermost layer of the cortex.

https://www.britannica.com/science/cambium

Cambium, plural Cambiums, orCambia, in plants, layer of actively dividing cells between xylem (wood) and phloem (bast) tissues that is responsible for the secondary growth of stems and roots (secondary growth occurs after the first season and results in increase in thickness).

https://www.quora.com/Why-is-cambium-absent-in-monocots

Cambium is absent in most of the monocots as they lack secondary growth. Unlike dicots the vascular bundles in monocots are scattered and they have an atactostele. Each vascular bundle has xylem arranged in the form of Y. Phloem elements are present on the outer side of xylem elements in between the two arms of Y.

Some of the similarities between the monocots and dicots include that both fall into the category of being a flowing and seed bearing plant and before germinate you can not determine the differences. Flower parts are divided usually in four and fives; the corolla is green; and calyx is separated from the petals.

https://www.dictionary.com/browse/eudicot

eudicot (yōō-dī′kŏt′) An angiosperm having two cotyledons in the seed, leaves with a network of veins radiating from a central main vein, flower parts in multiples of four or five, and a ring of vascular cambium in the stem. In contrast to most monocotyledons, eudicotyledons undergo secondary growth.

The characters which distinguish the classes. MONOCOTS DICOTS Embryo with single cotyledon Embryo with two cotyledons Pollen with single furrow or pore Pollen with three furrows or pores Flower parts in multiples of three Flower parts in multiples of four or five Major leaf veins parallel Major leaf veins reticulated

https://study.com/academy/lesson/cotyledon-definition-function-quiz.html

A cotyledon is part of the embryo within the seed of a plant. Often when the seed germinates, or begins to grow, the cotyledon may become the first leaves of the seedling. Botanists use the number of cotyledons present in the seed of a plant as a means of classification.

According to scientific researchers and DNA sequencing, the monocots are thought to be more advanced than dicots because of the following reasons: The dicots are thought to be older group of plants from which the monocots have evolved. The monocots have only one cotyledon while as dicots have two cotyledons.

Woody Dicot Stem. This particular type of dicot stem is composed of a cork, cork cambium, epidermis, cortex, xylem, phloem, vascular cambium, and a pith. The vascular cambium is a key characteristic in identifying woody dicots. It is responsible for the making and separation of both xylem and phloem.
