Every living being has a circulatory system irrespective of animals or human beings. Similarly, plants also have a venation system in their leaves. It is the arrangement of leaves in a specific pattern over a leaf. Herein, you will learn about the examples of parallel venation leaves with names.
Besides, you will also get to know about the various parts of a leaf through a diagram. Furthermore, we will also help you in learning the difference between parallel and reticulate venation with relevant diagrams and tables. Make sure you go through each section in detail to ace your NEET exam with good grades.
The word venation came from ‘veins’, and its arrangement in the leaves is termed accordingly. These veins are a present at the vascular tissue of a plant. These tissues emerge from their stem and run till the tip of a leaf. Look at the image below. It shows a common venation of a leaf.
As it is known, the stem constitutes both xylem and phloem. It also encloses the layers of covers around them. Those layers are parenchyma and sclerenchyma, which are again surrounded by the sheath cells. Although the primary function is the same, yet there are differences. These can be sorted by considering the examples of parallel venation leaves with names. Read along to find out.
As the venation runs from its stem till the leaves, they provide multiple benefits to the entire plant and also the leaves in particular. They are discussed below -
The venation runs till the tips of the leaves. They provide physical assistance to the leaves. It helps the blades in maintaining their shape and structure during their lifetime.
Leaves can coordinate with other parts of a plant due to the presence of venation. Also, it protects a blade as a whole.
Venation also helps in carrying the required nutrients to the leaves, which, in turn, helps them to grow. This also leads to the overall development of the blade.
Venation is different for leaves of different plants. This helps in identifying a specific plant by looking at the formation of the veins. Look at this image below. It shows various venation patterns.
Once a plant is identified through the venation of its leaf, the same can be used for classification purposes as well.
Therefore, by now, you are aware that venation is not consistent and can be different. Let us look deeper into the two most common types of venation - parallel and reticulate. Make sure to cover the examples of parallel venation leaves with names for a clearer understanding.
The characteristic features of parallel venation are listed below -
There is a parallel alignment of the veins in such leaves. Look at the image below, which shows parallel veins of a leaf.
Consider a banana leaf, which has a midvein. It also possesses parallel venation leaves that are perpendicular to the midvein. These veins run along with the entire leaf.
Now, refer to the image below. It shows reticulate venation. The veins do not run parallel to each other here. The image depicts the difference between reticulate and parallel venation.
In this case, there is only one midvein, and all the other veins have emerged from it. A fine example is that of the leaves of Mangifera species, the most common among them being Mangifera Indica (Mango). On another instance, there can be a network that is formed from the midvein in the entire leaf.
Vitally, do not forget to take note of such examples of parallel venation leaves with names.
Refer to the table for a comprehensive comparison of both kinds of venation.
Now, you have the differences along with examples of parallel venation leaves with names. The above table will help you in having a holistic approach to learning.
NEET demands you to have a stronghold on every topic that is included in syllabus. So, make sure you revise them thoroughly, including examples of parallel venation leaves with names. Also, jot down the vital points so that you can remember them longer.
Furthermore, also ensure that you are thorough with the difference between parallel and reticulate venation. It will not only help you retain what you have studied but also help you in answering short questions.
1. What is Parallel Venation?
Ans. Parallel venation is when the formation of veins are parallel to each other through the leaf. It starts from the base and extends till the tips.
For example, grasses; they have veins running parallel to each other.
2. What is Reticulate Venation?
Ans. Reticulate venation refers to the arrangement of veins in a leaf where they form a web-like structure. Smaller and more delicate veins emerge from the midrib and spread in the entire leaf.
For example, mango and rose leaves; their veins form a network.
3. What is the Prime Difference Between Parallel and Reticulate Venation?
Ans. The prime difference between reticulate and parallel venation is of their structures. While the former has a web-like appearance, the latter has a parallel structured appearance of veins.
