What is venation and its types?

Venation is the phenomenon of arrangement of veins in the lamina of the leaf surface. It is of three types, reticulate, parallel and furcate venation. In reticulate venation, veins form the network like structure. For example, leaves of dicot plants. In parallel venation, veins arise from the mid rib and run parallel.

What are the two types of venation?

There are two types of venation in a leaf. Reticulate venation— Veins form a network. Most of the dicot leaves are examples of plants with reticulate venation. Parallel venation–A parallel distribution i.e. veins run parallel to the midrib or parallel to each other.

What are types of leaf venation?

Leaf Venation Notes

• Reticulate Venation – In this type of venation, veinlets form a network. Reticulate venation is generally present in the dicotyledonous plants.
• Parallel Venation – In this type of venation, veins run parallel to each other. Parallel venation is generally a characteristic of monocotyledonous plants.

What are the types of venation in plants?

There are three types of venation namely Reticulate venation, Parallel venation and Furcate venation.

What is venation discuss the two types of venation in leaves of plants Class 6?

The arrangement of veins and veinlets on the lamina of a leaf is called venation. There are two types of venation, reticulate and parallel venation. Reticulate venation: in some leaves, the veins and veinlets are irregularly distributed over the entire lamina, forming a network.

What is parallel venation and reticulate venation?

Definition. Reticulate venation refers to the presence of interconnected veins, which form a web-like network whereas parallel venation refers to the presence of parallelly- running secondary veins to a central, perpendicular primary vein.

What are the types of venation with examples?

Parallel venation means that the veins run parallel to each other. Palmate parallel venation/multicostate parallel venation – several prominent veins, running parallel to each other….Parallel venation.

Parallel venation	Reticulate venation
Example
Bamboo, banana, grass, wheat, maize	Hibiscus, Ficus, Mango

What are the 3 types of leaf venation?

Three major venation patterns in simple leaves are “palmate”, “pinnate”, or “parallel” (Figure 17, left to right). Typically there is a prominent central vein (the midrib) running from the leaf base to its tip.

What is called parallel venation?

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.

What do you mean by leaf venation reticulate venation and parallel venation?

Two types of venation are reticulate venation and parallel venation. When the veins are irregularly distributed to form a mesh, it is known as reticulate venation. For example mango. When the veins are parallel and do not form a network, it is known as parallel venation.

What is rectilinear and parallel leaf venation?

Conclusion. Reticulate venation is the formation of web-like nerves of the leaf blade while parallel venation is the formation of parallel veins from the base to the apex of the leaf blade. Reticulate venation mainly occurs in dicots while parallel venation mainly occurs in monocots.

What is palmate venation?

Palmate is a venation pattern in which several main veins radiate outward from the base of the leaf. This pattern is similar to five fingers that spread out from the palm of our hand. Main veins are approximately equal in size. And they diverge from a common point where leaf blade and petiole unite.

What do you mean by reticulate and parallel venation?

Definition. When the veins are arranged in either web-like or network-like all over the lamina, it is known as reticulate venation. When the veins are arranged parallel to one another all over the lamina, it is known as parallel venation.

What are the 4 types of leaf arrangements?

The arrangement of leaves on a stem is known as phyllotaxy; leaves can be classified as either alternate, spiral, opposite, or whorled.

What are the 4 types of leaf margins?

There are many different types of leaf margins. A few examples include: Smooth (Figure 4), Saw-Toothed (serrate—Figure 5), very Irregular (Figure 6), and even Armed with sharp spines (Figure 7).

What are the 3 types of venation?

Venation is the phenomenon of arrangement of veins in the lamina of the leaf surface. It is of three types, reticulate, parallel and furcate venation.

What are the 5 types of leaves?

There are two different types of leaves – simples leaves and compound leaves. The other types of leaves include acicular, linear, lanceolate, orbicular, elliptical, oblique, centric cordate, etc. They perform the function of photosynthesis and help in the removal of excess water from the aerial parts of the plant.

What is reticulate and parallel venation?

Reticulate venation: in some leaves, the veins and veinlets are irregularly distributed over the entire lamina, forming a network. Such leaves are said to have reticulated venation. Parallel venation: in some leaves, the veins and veinlets run parallel to each other. Such leaves are said to have parallel venation.

What is the difference between parallel and reticulate?

Answer: Parallel venation is when the formation of veins are parallel to each other through the leaf. 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.
