Anatomy of Dicotyledonous and Monocotyledonous Plants

For a better understanding of how tissues are organised in the different organs of a plant, it is convenient to study the transverse sections of the mature zones of roots, stems and leaves. By cutting sections through the fully differentiated regions of these organs and examining them under the microscope, one can see clearly how the epidermal, ground and vascular tissue systems are arranged in each case.

Such a comparative study is especially useful because monocotyledonous and dicotyledonous plants, although both angiosperms, show marked differences in their internal organisation. These differences appear in the type, number and location of the vascular bundles, in the arrangement of the ground tissue, and in features such as the presence or absence of secondary growth. In the sections that follow, the anatomy of the dicot root, monocot root, **dicot s …
