What tissue occupies the center of the dicot stem?
cortex- In dicot stems, the cortex is located in the area between thevascular bundles and the epidermis. In monocot stems, it occupies the area surrounding the vascularbundles. The center of the stem is pith and may function as storage.
How are vascullar tissues arranged in dicot stems?
Vascular tissues in dicot stems are arranged in a ring formation, with the xylem located towards the center and the phloem on the outer side. This arrangement provides structural support and efficient transport of water and nutrients throughout the plant. Cambium, a meristematic tissue that gives rise to secondary growth, is located between the xylem and phloem in dicot stems.
The parenchyma cells inside the ring of vascular tissue in dicot stems are known as?
The parenchyma cells inside the ring of vascular tissue in dicot stems are known as pith. Pith cells are involved in storage of nutrients, water transport, and provide mechanical support to the stem.
Differences between monocot and dicot stem?
Monocot Root* Presence of thin walled cells in the epiblema. * Absence of cuticle and stomata.* Presence of unicellular root hairs.* Presence of passage cells and casparian thickenings in the endodermis.* Presence of parenchyma cells in the pericycle.* Presence of conjuctive tissue.* Presence of a distinct pith.* Presence of radial vascular bundles with polyarch condition and an exarch xylemDicot Root* Presence of thin walled cells in the epiblema. * Absence of cuticle, and stomata.* Presence of unicellular root hairs.* Absence of hypodermis.* Presence of passage cells and casparian thickenings in the endodermis.* Presence of uniseriate pericycle made up of parenchyma.* Presence of conjuctive tissue.* Absence of pith.* Presence of radial vascular bundles exhibiting tetrach condition with exarch xylemDicot Stem Anatomy:1. In dicot stem the epidermal multicellular stem hairs are present.2. Hypodermis present or absent; if present it is collenchymatous.3. Cortex is well differentiated.4. Endodermis and pericycle layers are present.4. Vascular bundles are arranged in a ring, they are conjoint, collateral, open and endarch.6. Pith is distinct and centrally located.Monocot Stem Anatomy:1. Usually stem hair are absent.2. Hypodermic generally present and it is sclerenchymatous.3. No cortex, the entire tissue below hyperdermis is ground tissue.4. No endodermis of pericylce.5. Vascular bundles are scattered in the ground tissue. they are conjoint, collateral and closed.6. Pith is not differentiated. (S_A)
What tissue surrounds and borders the stele of a dicot root?
The endodermis, a specialized layer of cells, surrounds and borders the stele of a dicot root. It is responsible for regulating the passage of water and nutrients into the vascular tissues of the root.
What tissue occupies the center of the dicot stem?
cortex- In dicot stems, the cortex is located in the area between thevascular bundles and the epidermis. In monocot stems, it occupies the area surrounding the vascularbundles. The center of the stem is pith and may function as storage.
Which plants are most receptive to tissue culture?
Dicot plants are more receptive to tissue culture due to the presence of cambium.

This arrangement provides structural support and efficient transport of water and nutrients throughout the plant.

What does the endosperm tissue of a dicot seed contain?
The endosperm tissue of a dicot seed contains nutrients such as starch, proteins, and lipids that provide energy and nourishment for the developing seedling. It serves as a food reserve to support the growth of the embryo during germination.
What is the difference between the arrangement of vascular tissue in the stems of dicots and monocots?
In young dicot and monocot stems do not increase in thickness. Xylem and phloem are arranged in vascular bundles in the cortex. In older stems and all woody stems, the vascular tissues form a cylinder between the cortex and the pith. The vascular bundles in a monocot are scattered throughout the stem.
Difference between monocotyledon and dicotyledon in stem?
1. at monocot stem. -stem hairs are absent. -sclerenchyma hypodermis. -internal tissue is not differentiated into different concentric layer but there is a common mass called ground tissue. -vascular bundles is found scattered in ground tissue. -presence of water cavity. 2. at dicot stem -stem hairs are present. -collenchyma hypodermis. -internal tissue is differentiated into hypodermis, cortex, endodermis, pericycle, medullary ray and pith. -vascular bundle is found between preicycle and pith. -water cavity is absent.

The endodermis, a specialized layer of cells, surrounds and borders the stele of a dicot root. It is responsible for regulating the passage of water and nutrients into the vascular tissues of the root.
How are vascular tissue arranged in dicot stems?
They form a ring where phloem forms an outer ring around the xylem.
Is there a pith in a monocot root?
Monocots do not have pith inside of them. They do have vascular bundles however, which are in a scattered order.
What are the differences between monocotyledonous and dicotyledonous root system?
Primary vascular bundles in dicot root are generally less than six whereas in monocot root it is generally more than six. Secondary growth does not take place in monocot roots; in dicot roots it is invariably takes place.
