The Italian physician and biologist Marcello Malpighi (1628 1694) was the first to use the term cotyledon (the Latin word meaning seed leaf) and John Ray (1627 1705), an English naturalist, was the first to notice that some plants have one cotyledon and others have two. Core Differences between Dicot Root and Monocot Root In Point Form Dicot root has planted with two cotyledons while monocot root has planted with a single cotyledon. Dicot leaves are also called as dorsiventral leaves because they possess distinct dorsal and ventral sides. (c) 1. Monocot plants have single cotyledons whereas dicot plants have two cotyledons. 18. The Dicots' veins start at the bottom and branch out in an ordered network all over the leaf (as in a rose). 21. 2. The information is "AS IS", "WITH ALL FAULTS".

The leaves of a hibiscus have a stalk so it is a dicot. (a) 1. Outside the outer cambium is present a patch of outer phloem, and inner to the inner cambium is present the inner phloem, thus representing the open and bicollateral condition of vascular bundles. (i) Outer cambium is flat and many-layered. Rest of the portion is filled with may large, thin­walled, parenchymatous cells which form ground tissue. Secondary phloem is present inner to the primary phloem. Single-layered epidermis consists of many barrel- shaped cells covered with cuticle. The leaves are usually ribbon like with parallel venation. The outer wall of cells is covered by a thick cuticle. Monocotyledons and dicotyledons, also known as monocots and dicots, respectively, are two types of angiosperm plants. Normal Dicotyledonous Stems 4. (ii) Phloem fibres and phloem parenchyma are absent. Vascular bundles are of different size. Primary root formed from radicle is replaced by a adventitious fibrous roots. 2.
