Background and aims: Acropetal root branching is a major process which increases the number of growing tips and distributes their growth potential within the whole root system. If it is a question of wood forms, that is a trunk and branches. Based on the number of Cotyledons, Seeds are divided into two types: They are Monocotyledonous and Dicotyledonous. Dicot plants have the taproot system. They have a double perianth (sepals and petals), flowers predominantly five- or four-membered. Some seeds have been documented having a triploid endosperm. Dicot Root: The Xylem they possess is in the ‘X’ shape, and it I surrounded by the phloem. Dicots have a tap root system which is the primary root system, while monocots have a fibrous root system that looks like fiber, and is also known as an adventitious root system. Plants have evolved various defences to lessen the impact of predation by herbivores. This video describes about monocotyledonous root consist of epidermis, cortex, endodermis, pericycle, vascular bundles and pith. Dicotyledons: The Dicotyledons have tap root system. In monocotyledonous plants, despite the efforts to identify sources of resistance to nematodes, only a few R genes have been genetically mapped (Mc Donald and Nicol, 2005, Smiley and Nicol, 2009) and none of them, to our knowledge, have been cloned ().In parallel to the R gene mapping, breeders have identified plant accessions that present resistance or tolerance to nematodes.
