Difference between Dicot and Monocot Stems, Difference between Dicot Root and Monocot Root | Plants, Monocot and Dicot Roots (With Diagram) | Plants. 2. Formation of four furrows of secondary phloem in the secondary xylem is due to the abnormal functioning of cambium which was behaving normally sometime earlier. Primary xylem is situated just near the pith facing its protoxylem towards the centre. 2. Both monocot and dicot leaves have an outer, waxy layer referred to as cuticle that covers the dermal tissue of the upper and lower epidermis. The upper and lower surfaces of these monocot leaves are of the same color. Monocots and Dicots: Characteristics and Differences Plants can be broadly divided into two types: flowering plants and non-flowering plants. Monocot Stem with Secondary Thickenings 3. Collenchyma is present below the epidermis in the ridges in young stem but at maturity there develops sclerenchyma. In the case of monocot stems, they come with scattered vascular bundles. (3, 7, 8, 9) For a brief comparison of the difference between monocot and dicot, refer to the table below. 7. is circular in outline and reveals the following tissues from outside with-in: 1. Angiosperms are divided into two subgroups, dicotyledonous and monocotyledonous plants, mainly on the basis of number of embryonic leaves or cotyledons. 14.

In the young stem, vascular bundles are conjoint, collateral, open and endarch but old stems show secondary growth. One is called monocotyledons or monocot and the other is called dicotyledons or dicot. 21. Xylem consists of wide vessels present on the outer side representing the metaxylem and narrow vessels present towards inner side representing the protoxylem. Seeds are generally formed as the end product of sexual reproduction in plants and are exclusively found in angiosperms and gymnosperms. Primary xylem is present near the pith facing its protoxylem towards the centre of stem. There are certain differences between the anatomy of monocot and dicot plants. 16. 8. In the pericycle region, extrastelar cambium strips develop which produce secondary vascular bundles. It bears many multicellular hair when young. Next to the collenchyma is situated the region of parenchyma, consisting of many thin-walled, oval to spherical cells with intercellular spaces. It consists of primary phloem, secondary phloem, cambium, secondary xylem, interxylary phloem, primary xylem and intraxylary phloem. In the later stages the stem shows secondary growth. Many conjoint, collateral, open and endarch bundles are present in the pith. 6. Learn vocabulary, terms, and more with flashcards, games, and other study tools. ADVERTISEMENTS: 3. The basis of comparison include: […] Dicot leaves have thick cuticle at the upper layer and thin cuticle at lower layer whereas monocot leaves have uniform cuticle on both the surfaces. Inner to the endodermis is present parenchymatous pericycle but at some places it is represented by isolated patches of sclerenchyma. (a) 1. Tracheids and vessels are also present. The differences between dicot root and monocot root can only be understood when you have clear information about angiosperms plants. Secondary cortex is either parenchymatous or chlorenchymatous. 15. Whereas, a dicot will grow two leaves as its seed contains two cotyledons. It is represented by thick, sclerenchymatous stone cells forming a discontinuous layer. Dicot Seed. 6. Flowers are generally pentamerous or tetramerous (floral parts in sets of 5 and 4 or their multiples). In old stems is present the periderm which consists of cork, cork-cambium and secondary cortex. 13. This is the key difference between monocot and dicot stem.. Monocot plants and dicots plants possess many differences both structurally and functionally. The venation of dicot leaf is reticulate whereas monocot leaf has parallel venation. Cork consists of rectangular and dead cells. On the other hand, in dicots stem, the vascular bundles are arranged in the form of one or two broken rings, following that they have a definite shape.
