The embryology of flowering plants is divided into two distinct courses, the monocots and the dicots. The phrase “cradle” is derived from cotyledons (vein), meaning leaves. If it has one leaf, it is called a monkey cotyledon, while if it has two, it is often called a Dicot. Plants differ not only in leaves, but also understand the root, stem, and flowers correctly. The main thing between a Monocot stem and a Dicot stem is that, Monocot organizes the vascular tissue “sporadically” whereas Dicot organizes it in a “donut” shape and differentiates correctly. The stem is responsible for supporting the entire plant and helps it realize as much daylight as possible for photosynthesis.
What is Monocot Stem?
A Monocot stem is delimited by a layer of dermis. This dermis is made up of highly organized rectangular cells. Protect the plant from the outside environment. It incorporates a waxy substance known as cutin. This cutin is responsible for forming a cuticle layer that stops excessive water loss from the plant. Then there is the hypodermis, which is made up of sclerenchymal cells. There is no clear demarcation between the cortex and the vascular bundles are spherically dispersed using the tissue from the bottom. The sclerenchyma sheath delimits the vascular bundles. They are collateral and closed. The phloem is present on the outside of the xylem. The xylem is y-shaped. Metaxylem at the 2 ends of y, and two protoxylems at its base. Protoxylum disintegrates to form a lysogenic cavity. There is no secondary progress. Examples of monocots are wheat, corn, rice, and sugar cane.
Dicot stem is secure by dermis layer. You have trachoma and stomata present. Next to the dermis is the cortex. The cortex is correctly differentiated into three completely different areas. The upper part is hypodermis, formed by cholenchymal cells that strengthen the young stem, the heart is a regular cortex, formed by parenchymal cells with a large intercellular home and, in addition, it has resin channels. Its function is that of a food retailer. Most of the inner layers are endodermis, made up of barrel-shaped starch cells. In addition, it has a paricycle layer that separates the cortex from the vascular bundles. The vascular bundles are organized in a ring. They are joint, collateral, open and closed. Open means that there could also be cambium between the xylem and the phloem. The metaxylem is in the peripheries and the protoxylem is in the path of the center of the stem. Medullary rays between adjoining medullary buildings. They are responsible for changing meals. The central tissue is the medulla, in the main part it expels the food, but in the second place mechanical energy is given to the stem. Examples of dicots are pea, rose, apple, sunflower, and sarson, etc.
- Monocot has one cotyledon and Dicot has two.
- In the dermis or monocots, the trochomes are absent and the cuticle is present, while in Dicot it has all.
- In monocots, the hypodermis is made up of sclerenchymal cells, while in dicots it is made up of cholenchymal cells.
- The soil tissue of monocots does not differentiate, whereas in dicots it differentiates into cortex, endodermis, pericycle, medullary rays and medulla.
- There are quite a few vascular bundles in monocots, while there are eight in dicots.
- The vascular bundles are irregularly scattered in monocots, while inside the broken ring type in Dicot.
- The top of the pack is absent in monocots while it is present in dicot.
- The bundle sheath is present in monocots while it is absent in dicot.
- Vascular bundles in monocots are joint, collateral and closed with endarch xylem, while in dicot they are joint, collateral and open with xylem endarch.
- Monocot has only two protoxylems in each package, while Dicot has many.
