Cut a transverse section of young stem of a plant
8.4: Monocots. Monocots are a group of flowering plants that produce a single first leaf ( cotyledon) as their seeds germinate. Eudicots (frequently referred to simply as dicots) produce two cotyledons. In addition to this feature, monocots and eudicots can be distinguished by several anatomical and morphological features.

The anatomy or internal structure of a monocot stem can be studied by a Transverse Section (T.S.) taken through the internode of a monocot plant such as grass, bamboo, maize, Asparagus etc. The main difference of monocot stem from dicot stem is that, here in monocots the ground tissue is NOT differentiated into Cortex and Endodermis.
Internal structure of monocot stem
Dicot Stem The dicotyledonous stem is usually solid. The transverse section of a typical young dicotyledonous stem consists of the following parts: The epidermis is the outermost protective layer, which is covered with a thin layer of cuticle. Epidermis possesses trichomes and a few stomata.
monocot stem anatomy
The monocot stems have other significant features: lack of trichomes (epidermal hairs), medullary rays, cortex or pith, and a stele. Also, the hypodermis consists of sclerenchyma cells. Monocot Stem. The dicot stems are stems of dicot plants. They are arranged concentrically, one above the other. The vascular bundles of dicot stems are arranged.

Monocot Stem: Tissue # 1. Epidermis: It is the outermost layer of the stem which is made up of compactly arranged transparent, elongated and rectangular—barrel-shaped living parenchyma cells. The outer walls of epidermal cells possess deposition of silica and cutin. A separate layer of cuticle also occurs on the outside.

Monocot and Dicot Stems (With Diagram) | Plants Article Shared by ADVERTISEMENTS: The following points highlight the top four types of monocot and dicot stems. The types are: 1. Normal Monocot Stems 2. Monocot Stem with Secondary Thickenings 3. Normal Dicotyledonous Stems 4. Anamalous Dicotyledonous Stems. Monocot and Dicot Stems: Type # 1.

Distinguish monocot and dicot stems based on the arrangement of the vascular bundles. Describe the functions of some of the specialized cells in the stem.

Hypodermis Ground tissues Vascular bundles Transverse Section of Internal tissues organization of Monocot Stem (Maize) Epidermis is the outermost uniseriate cuticularised layer of parenchyma with stomata. It is made from arranged barrel shaped cells usually without epidermal stem hairs.
monocot stem anatomy
T.S. of a monocot stem shows the following anatomical features: Epidermis: It is the single outermost layer composed of small, thin-walled, somewhat barrel-shaped parenchymatous cells which are tightly packed without intercellular species. It is externally covered with thick cuticle. A few stomata are present on epidermis.

Roots. The roots allow plants to absorb water and nutrients from the soil. Monocot roots are fibrous, meaning they form a wide network of thin roots that originate from the stem and stay close to the soil surface. Dicot roots have a central "taproot," meaning they form a single thick root, with lateral branches, that grows deep into the soil.
Draw a labelled diagram of vascular bundle of a monocot stem.
Structure of Monocot Stem | Botany Article Shared by ADVERTISEMENTS: In this article we will discuss about the internal structure of monocot stem with reference to a typical monocotyledon, the maize stem, and carina scape. 1. Maize Stems (Figs. 150 & 151): I. Epidermis: It is as usual single-layered with cuticularised outer walls. ADVERTISEMENTS:
Cross Section Of A Monocot Stem
Let's grow! A look at monocot and dicot stems 1. The stem supports the plant, facilitates water and nutrient transport between the different parts of the plant, and contains tissues that help the plant grow. The stem supports the plant, holding up the plant's leaves, flowers, and fruits.
Differences between Dicot and Monocot stem Online Science Notes
In monocot stems, the vascular bundles are randomly scattered throughout the ground tissue. Figure \(\PageIndex{1}\): Vascular bundles: In (a) dicot stems, vascular bundles are arranged around the periphery of the ground tissue. The xylem tissue is located toward the interior of the vascular bundle; phloem is located toward the exterior.
