The specimen provided is a section of a dicot stem. To study of the transverse section of monocot root, maize root. Under the endodermis is a thin-walled layer of cells known as pericycle. (c) General Cortex (Parenchyma) – Located just under the hypodermis, it consists of several layers of cells that are living having thin walls along with intercellular spaces. They are densely arranged single cell layer. Ensure, that the air bubbles are not formed while mounting. After a while, drain the sections of the stain and rinse again with water so as to wash off the excess strain. The xylem is endarch with the protoxylem being at the centre and the metaxylem being at the periphery. The outer pericycle, endodermis, cortex and epidermis are the same in the dicot root. We shall explore the differences between monocot and dicot leaf in this article. Shift it to a different watch glass holding safranin stain. Let the complete set rest in the stain for a couple of minutes. The embryonic axis comprises everything between the plumule and the radicle, not including the cotyledon(s). Slice it into thin sections. To study of the transverse section of monocot root, maize root. In tissue, it forms the central core having a vascular bundle. Buy for Rs.100.

Monocot Roots and Dicot Roots. It may contain chloroplast and hence becomes photosynthetic. The root hairs are seldom seen because when a plant is … Therefore, the term “monocot” refers to the flowering plants that contain only one cotyledon. Liver fluke. Made up of two of these three layers, Consists of thin-walled living cells, parenchymatous cells, Loose arrangement of cells with the presence of intercellular spaces, As seen in the dicotyledonous stem, there is no differentiation of cortex, pericycle and the endodermis, Several scattered vascular bundles found in the ground tissue and are closed type, collateral and conjoint, At the periphery, the vascular bundles are more and densely arranged when compared to the center, Large vascular bundles in the center compared to vascular bundles at the periphery, They resemble an oval shape that is girdled by sclerenchymatous bundle sheath, Metaxylem are present at the two lateral arms. These are cells that have the cellulose deposits on the edges and are living cells. Required fields are marked *, Preparation And Study Of Transverse Section Of Dicot And Monocot Roots And Stems.

They are open, collateral and conjoint and are set up in a ring-like manner. Question.3 Define the terms and give one example of each: (a) Bilateral symmetry (b) Coelom (c) Triploblastic Answer. Your email address will not be published. To prepare a temporary stained mount of a transverse section of dicot and monocot stem and root to study various plant tissues. Small as well as large vascular bundles are present, Due to the presence of mesophyll cells, dicot leaves have large intercellular spaces, Monocot leaves have comparatively tighter intracellular space due to the compact arrangement of mesophyll cells, Differentiated into two parts – upper palisade and lower spongy mesophyll, No such differentiation in a monocot leaf, Parallel venation (Veins do not join other veins). It consists of radial bundles having alternating 2 to 6 arrangement of bundles of phloem and xylem, Bundles of xylem are exarch wherein the metaxylem is present towards the center and the protoxylem at the outer side, Comprises of companion cells, parenchyma and sieve tube, They are the parenchyma cells that separate the, They are significantly absent or occur rarely, The epidermis shows the presence of unicellular hair, The number of phloem/xylem bundles is not more than 6, The transverse section is circular having a smooth surface, The ground tissue consists of many scattered vascular bundles. Differentiate between monocot and dicot plants on the basis of venation patterns. Located between the vascular bundles and endodermis. They are composed of starch grains.

(a) Hypodermis – It is situated just below the epidermis and consists of 4 to 5 layers of collenchymatous cells. They are barrel-shaped forming the innermost layer of the cortex. Somewhere between 1 to 2 billion years ago, a free-living cyanobacterium entered an early eukaryotic cell, either as food or as an internal parasite, but managed to escape the phagocytic vacuole it was contained in. Therefore, the term “monocot” refers to the flowering plants that contain only one cotyledon. 5. Study the following parts of human skeleton (Model): Ball and socket joints of thigh and shoulder 6. This gap finds parenchymatous cells that are thinly walled and arranged radially in 4-5 rows. Likewise, the term “dicot” refers to flowering plants having two cotyledons.

The cells in the region of elongation gradually mature after differentiation and form the region of maturation. Figure 23. Roots and underground organs.
