At four or more places cambium produces less amount of secondary xylem towards inner side and large amount of secondary phloem towards outer side. Inner to the endodermis is present parenchymatous pericycle but at some places it is represented by isolated patches of sclerenchyma. Phloem consists of sieve tubes, companion cells and phloem parenchyma. 12. It bears many multicellular hair when young. These bundles get embedded in the thick prosenchyma and their phloem appears as included or interxylary phloem. … 18. Dicot root has a tap root-like structure and they are narrower while monocot root has a fibrous root-like structure which is comparatively larger. So for the orchid plant there’s … The types are: 1. ADVERTISEMENTS: The below mentioned article provides study notes on Secondary Growth in Dicot Stem of plants. ………Dicot. Vascular bundles of innermost and middle rings are medullary bundles. These bundles may show secondary growth at maturity. 2. Monocot stem refers to the stem of the monocot plants characterized by the presence of scattered vascular bundles while dicot stem refers to the stem of the dicot plants characterized by the presence of vascular bundles arranged in rings. Endodermis is undistinguishable from cortical cells. The cells are filled with chloroplasts and show many intercellular spaces. Following are the substantial characters to distinguish between the two types of angiosperms: Monocots can be defined as the plants with the seed having only one cotyledon, and the plant is called as monocotyledons, while plants with the seed having two cotyledons are called as dicots, and the plant is called as dicotyledons. 1. is circular in outline and reveals the following tissues from outside with-in: 1. Interxylary phloem and medullary bundles are present. 3. Dicot – The seedpod varies in shape, size, and texture. Monocot – It only has one cotyledon in its embryo. The basis of comparison include: […] Sometimes they develop chlorophyll. It is wavy in outline. 13. 5. Example- Corn seed Presence of sclerenchymatous patches in the ground tissue. 4. A big zone of pericycle is present below the endodermis consisting of parenchymatous cells. Dicot plant has two cotyledons in each seed while monocot plant has one cotyledon in each seed. It is differentiated into collenchyma and parenchyma. Chlorenchyma is present inner to collenchyma in the form of 3 to 7 layers. Single-layered epidermis consists of compactly arranged thin-walled cells and is covered by thick cuticle. In the later stages the stem shows secondary growth. Thin-walled parenchymatous cells of ground tissue form the pith. The continuity of the layer is broken by few stomata. Stem. Main Difference. 12. Primary xylem consists of protoxylem and metaxylem. Primary phloem is crushed and present in small patches. This is the key difference between monocot and dicot stem.. Monocot plants and dicots plants possess many differences both structurally and functionally. 10. Monocot leaf has a large vascular bundle while dicot leaf has both small and large vascular bundles.

Draw necessary diagram. 18. Monocot vs. Dicot. It consists of four to five layers of thick- walled, lignified sclerenchymatous zone present just below the endodermis. Monocots are divided into several taxonomic ranks and include approximately 60,000 species. 8. Cambium produces the conjunctive tissue. Monocot Stem with Secondary Thickenings 3. One is called monocotyledons or monocot and the other is called dicotyledons or dicot. These are also known as phellem, phellogen and phelloderm, respectively. 173) from outside with-in: Epiblema: 1. Accordingly, dicot produces two leaves during the seed germination while the monocot produces one leaf during the seed germination. 11. Collenchyma is present below the epidermis in the ridges in young stem but at maturity there develops sclerenchyma. Which organelle is known as “power house” of the cell? Multicellular epidermal hair ………..Stem. 6. 19. It consists of primary phloem, secondary phloem, cambium, secondary xylem, interxylary phloem, primary xylem and intraxylary phloem.

It consists of primary phloem, secondary phloem, cambium, secondary xylem and primary xylem. Xylem consists of vessels and tends to occur on the upper epidermis. Furthermore, monocot leaves are bicollateral leaves while dicot leaves are dorsoventral leaves. Difference between Dicot and Monocot Roots, Stems . A ring of vascular bundles is present in the primary state which are conjoint, bicollateral, open and endarch. Chlorenchymatous cells are thin-walled, oval, full of chloroplasts and enclose many intercellular spaces. This type of root system is known as the adventitious root. These are called medullary bundles. The differences between dicot root and monocot root can only be understood when you have clear information about angiosperms plants. 7.
