Primary tissues include […] Example: Grasses, sugarcane, maize and wheat. In addition, most promoter regions in mitochondria of monocots may have a small upstream element in common, a purin-rich region located at position − 12 to − 9 (Rapp et al., 1993; Tracy and Stern, 1995) resembling the structure of the P. Pericycle is absent in roots and stems of some aquatic plants. Monocotyledonous Plants. Generally, dicotyledonous plants have tap roots while monocotyledonous plants have fibrous roots. The leaves of the dicot plants have veins that form a branched pattern, unlike monocots, in which they run parallel. Parallel venation is where the secondary veins run parallel to each other and are connected laterally by the minute and straight veinlets. The association is mutualistic; that is, both the fungus and the root benefit from it and are dependent upon the association for survival.

The monocotyledonous plants have the adventitious or the fibrous type of root system that do not grow much deeper but spread in the region widely to provide support the plant. Features of monocot and dicot plants. Answer: Belonging to the Pteridophyta group, ferns have well developed roots, stem and leaves and even separate tissues for conduction of food and water.However, they do not produce flowers and fruits. They can differ in the number of bundles or other minor details viz., in Maize root there is present sclerenchyma outside the phloem bundles (Fig. Essential for normal growth and development and they facilitate the uptake of water and inorganic ions. Monocots are known to have adventitious roots whereas dicots have a radicle from which a root develops. Dicotyledonous and Monocotyledonous Roots Dicot Root. In contrast, dicots have a taproot system, a tapering root that grows downward and has other roots sprouting laterally from it. Pith Root Cap. Species: Monocotyledon is a smaller group of flowering plants with 60,000 species of plants. The roots in some plants get modified for storage of food, mechanical support and respiration. They reproduce with the help of spores that are formed along the back or posterior surface of their leaves. The term monocot is short for monocotyledon. A seed contains all the things that are necessary for the growth and development of a new plant. Bermuda grass 5. The roots do not have a cambium and cannot enlarge in diameter. Pine apple 11. Banana 3. Subject: Biology. In monocotyledonous plants, as well as few dicotyledonous plants, fibrous roots are present. (B) Other Monocotyledonous Roots: The structure of most of the roots is similar to that of Canna root. Seeds that have one seed leaf (corn or rice), commonly referred to as monocots, and have fibrous root systems. Monocotyledons: The number of individual parts of the flowers is … Let’s take a look at the anatomy of dicotyledonous and monocotyledonous plants. While, monocot root contains xylem and phloem in another manner, forming a circle. In monocot roots, xylem and phloem tissue bundles are arranged in a circular fashion around the central pith, which consists of ground tissue (parenchyma). Formation of Lateral Roots : In flowering plants, the lateral roots are endogenous in origin, that is, they originate in the inner tissue of the mother root, and appear externally only after their growth is well begun. Desho grass (Pennisetum pedicellatum) 5. 7. Many people take this separation into two classes for granted, because it is "plainly obvious", but botanists have not always recognized these as the two fundamental groups of angiosperms. Monocot and Dicot differ from each other in four structures: leaves, stems, roots and flowers.The difference between dicot and monocot root is, dicot root contains xylem in the middle and phloem surrounding it. Monocotyledonous plants are also referred to as monocots. The veins are actually netted or webbed on the whole surface of the leaf. Tap root system; Adventitious root system; Fibrous root … 4.
