Difference between Parallel Venation and Reticulated Venation

Key difference

The key difference between parallel venation and reticulated venation is that in parallel venation, the veins are arranged in parallel in a leaf, while in reticulated venation the veins are in web-like structure.

Parallel venation versus reticulated venation

A well-developed transport system is a basic need for multicellular organisms. Like other organisms, plants have a transport system in the form of xylem and phloem. Xylem is used to transport water, while phloem is used to transport nutrients, sugar or food, etc. throughout the body of the plant. The xylem and phloem are collectively known as vascular bundles. They also provide support to the plant. Like other parts of the plant, i.e. stem, root, etc., vascular bundles are also present on the leaf. In the leaf blade, vascular bundles are present in the form of a vein. A vein is made up of xylem and phloem surrounded by parenchyma and bundle sheath cells. Each species of plant has a specific arrangement of these veins known as a venation pattern. The venation pattern plays an important role in the recognition of different plant species. There are two basic types of venation pattern, namely, parallel venation and reticulated venation. In parallel venation, the veins are arranged parallel to each other in the leaf blade from base to tip, while in reticulated venation, the veins are arranged in the form of a network.The main vein entering the leaf from the petiole is known as the primary vein or midrib, while the veins that arise as branches from the primary vein are known as secondary veins. Parallel venation is found in monocots, while reticulated venation is found in dicots. The main vein that enters the leaf from the petiole is known as the primary vein or midrib, while the veins that arise as branches from the primary vein are known as secondary veins. The parallel venation is found in the monocots, while the reticulated venation is found in the dicots. The main vein that enters the leaf from the petiole is known as the primary vein or midrib, while the veins that arise as branches from the Primary vein are known as secondary veins. Parallel venation is found in monocots, while reticulated venation is found in dicots. while the veins that arise as branches of the primary vein are known as secondary veins. The parallel venation is found in the monocots, while the reticulated venation is found in the dicots.

Comparative chart
Parallel venation Reticulated venation
A type of leaf venation pattern in which the veins are arranged parallel to each other from the base to the tip of the leaf is known as parallel venation. A type of leaf venation pattern in which the veins are arranged in a web or web like a pattern on the leaf is known as reticulated venation.
Type of Plants
The parallel venation is found in monocots. Reticulated venation is found in dicots.
Orientation of the veins
The veins are arranged parallel to each other in parallel venation. Veins produce a network-like structure in reticulated venation.
Types
It is divided into two main types, that is, pinnate parallel venation and palmate parallel venation. Reticulated venation is also divided into two main types, namely pinnate reticulated venation and palmate reticulated venation.
Examples
Banana, grass, and bamboo show parallel venation. Ficus, hibiscus and mango have reticulated venation.

What is parallel venation?

A type of venation pattern in which the veins are arranged parallel to each other from the base to the tip of the leaf blade is known as a parallel venation. It is found in monocots. It is divided into two main types, that is, pinnate parallel venation and palmate parallel venation.

  • Parallel pinnate venation : In the parallel pinnate vein, there is a prominent midrib in the center of which many veins arise perpendicularly and run parallel to each other. For example, banana.
  • Parallel clap venation : In parallel clap venation, many veins arise from the tip of the petiole and run parallel to each other. Again it is divided into two types, that is, convergent parallel venation and divergent parallel venation. In convergent parallel venation, all veins that run parallel to each other converge at the apex and their example is grass. In divergent parallel venation, the leaf blade is lobed, so the veins diverge to enter separate lobes at the base and its example is Borassus (Palmyra).
What is reticulated venation?

A type of venation pattern in which the veins are arranged in a web or a web-like pattern in the leaf blade is known as a reticulated venation. It is found in dicots. Reticulated venation is also divided into two main types, namely pinnate reticulated venation and palmate reticulated venation.

  • Venation crosslinked pinnada : In the reticulated venation pinnate, a central rib is only present while all other branches form a netlike structure. Also called unicostat cross-linked venation. His example is Mangifera.
  • Reticulated palmate venation : In the reticulated palmate venation, many central veins are present and other veins form a network-like structure. Also called multicostat reticulated venation. Furthermore, it is divided into two types, that is, convergent reticulated venation and divergent reticulated venation. In convergent reticulate venation, the main veins converge toward the top of the leaf apex, while in divergent reticulate venation the main veins diverge.

Key differences

  1. A type of leaf venation pattern in which the veins are arranged parallel to each other from the base to the tip of the leaf is known as parallel venation, while a type of leaf venation pattern in which the veins They are arranged in a web or web as a pattern on the leaf is known as reticulated venation.
  2. Parallel venation is found in monocots, while reticulated venation is found in dicots.
  3. The veins are arranged parallel to each other in parallel venation, whereas the veins produce a branched or web-like structure in the reticulated venation.
  4. Banana, grass, and bamboo are some examples of parallel venation, while ficus, hibiscus, and mango are examples of reticulated venation.
Final Thought

From the above discussion, it is concluded that the parallel venation and the reticulated venation are the venation patterns on the leaf. In parallel venation, the veins are arranged parallel to each other in the leaf blade and are found in monocots. Reticulated venation has a network-like arrangement of veins and is found in dicots.
