Historically, plants are classified into two categories based on the number of cotyledons or embryonic leaves. In the old stem, the vascular system consists of primary phloem, secondary phloem, cambium, secondary xylem, conjunctive tissue, included phloem and primary xylem. (a) 1. Dicots: ADVERTISEMENTS: They are angiospermic or flowering plants which are … In the mature stems showing secondary growth, cork cambium is present which cuts cork towards outer side and secondary cortex towards inner side. A thick cuticle covers the outer wall of the cells of epidermis. The monocot plant has just a bunch of roots. At the time of secondary growth many-layered cambium (meristematic tissue) develops outside the primary bundles in the parenchyma. Vascular bundles are conjoint, collateral, open and endarch.

Monocots and Dicots: Characteristics and Differences Plants can be broadly divided into two types: flowering plants and non-flowering plants. These are called interxylary phloem or included phloem patches. Monocotyledons and dicotyledons, also known as monocots and dicots, respectively, are two types of angiosperm plants. (c) 1. Whereas, a dicot will grow two leaves as its seed contains two cotyledons. It is wavy in outline. Collenchyma is present below the epidermis in the ridges in young stem but at maturity there develops sclerenchyma. Secondary xylem and conjunctive tissue are undistinguishable. A big zone of pericycle is present below the endodermis consisting of parenchymatous cells. Due to the intrusion of the phloem at four places, secondary xylem is ridged and furrowed at four places. Pea, beans, peanuts, tomato, brinjal, oak leaf, etc. Collenchyma is present only below the ridges and its breadth and depth varies below different ridges. A few multicellular hair are also arising from some cells. Difference # Dicots: 1. (a) 1. Endodermis is the innermost layer of cortex.

Examples of dicot seeds are - Mango, Peanut, Pea etc. In the case of monocot stems, they come with scattered vascular bundles. Another main difference in monocot and dicot leaf is that monocot leaf has an equal number of stomata on either side, but dicot has more stomata at its lower surface. Primary xylem is present near the pith facing its protoxylem towards the centre of stem. Share Your PDF File The information is "AS IS", "WITH ALL FAULTS". Their development is centripetal. It consists of primary phloem, secondary phloem, cambium, secondary xylem and primary xylem. 2. 3. Normal Monocot Stems 2. From some cells arise multicellular hair. A monocot leaf possesses stomata on both the epidermis layers and they generally have undifferentiated mesophyll. 2. Monocot Stems. 13. Do you compare the shapes of the leaf or the type of stem? It consists of primary phloem, secondary phloem, cambium, secondary xylem, interxylary phloem, primary xylem and intraxylary phloem. Xylem and phloem constitute the vascular bundle. Many intercellular spaces are present. Monocot and dicot plants contain stomata in their leaves as well as in their stem. Multicellular epidermal hair arise from some cells. It consists of cortex, chlorenchyma, patches of sclerenchyma and ground tissue. 16. In both monocot and dicot leaves, the vascular bundles are conjoint and collateral.
