What are the 3 types of leaf veins?
The arrangement of veins in a leaf is called the venation pattern; monocots have parallel venation, while dicots have reticulate venation. 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 different types of leaf 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.

| Bamboo, banana, grass, wheat, maize | Hibiscus, Ficus, Mango |
What are the two types of venation give example?
Give its types. Reticulate venation – Reticulate venation includes irregular vein arrangement for the creation of a network. Parallel venation – Parallel venation means that the veins run parallel to each other.
How many types of venation are there?
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.
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 are leaf veins called?
This vein is called the midrib. All of the veins, the petiole, and the midrib help position the blade so that it is facing the light source. Veins of flowering plants are found in several patterns.
What is whorled arrangement of leaves?
A plant has whorled leaves when there are three or more equally spaced leaves at a node. In angiosperm: General features. … outside) there would be a whorl of five sepals, followed by an alternating whorl of five petals, followed by an alternating set of five stamens.
What is divergent venation?
In this, lamina has more than one principal vein. It is further divided into divergent reticulate venation and convergent reticulate venation. In divergent venation, the major veins diverge towards the tip. Examples include Castor, cotton. In convergent venation, the major veins converge towards the tip.
What is Pinnately and Palmately?
Pinnate refers to a condition of compound leaves with twig-connected petioles of varying lengths and rows of smaller sub-leaves above the axil while palmate refers to a condition of compound leaves, having leaflets form and radiate from a single point of attachment called the distal end of the petiole or rachis.
What is parallel venation give an example?
Parallel venation: In some leaves, the veins run parallel to each other. Such leaves have are said to have parallel venation. Example: banana, grass and wheat. Reticulate venation: In some leaves, the veins and veinlets are irregularly distributed over the entire lamina, forming a network.
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 lamina in leaf?
The lamina is the green flat part of a leaf that is specialized for photosynthesis.
What are the different types of venation in trees?
Types of Venations for Trees. 1 Parallel Venation. Banana leaves have obliquely parallel venation. 2 Palmate-type Reticulate Venation. 3 Pinnate-type Reticulate Venation. 4 Dichotomous Venation. 5 Venation in Conifers.
Where is venation found in plants?
Venation is found in leaves. In venation there is the system of veins which contains minerals and water from soil to leaves. Venation is of two types :- parallel and reticulate venation. In this venation, veins runs parallel to each other.
What is parallel venation in plants?
Parallel Venation: In this type of venation all the veins run parallel to each other. Most of the monocot leaves have parallel venation. It is of two types. a. Pinnateley Parallel venation : In this type, there is a prominent midrib in the centre.
What is reticulate venation in plants?
Reticulate venation is a pattern of branching veins in the leaves. There are three types of reticulate venation: parallel, collateral, and net-like. Parallel reticulate venation has two or more sets of veins that run side by side on the leaf surface. In this type, both sets of veins originate from one point at or near the leaf blade base.
