Simple And Compound Leaves

Understanding leaves to help identify trees. Biology for class 11and 12 discuss differences between a simple and compound leaf.

The Difference Between A Simple And Compound Tree Leaf

Compound leaves have a division of lamina whereas simple leaves do not have.

Simple and compound leaves. On the other side compound leaves comprise their stalks and show an attachment with the middle vein. The main difference between simple leaf and compound leaf is that the simple leaf has an undivided leaf blade while the leaf blade of a compound leaf is divided into several leaflets. The base of a simple leaf contains stipules but in compound leaf the stipules are found at the base of the leaf but other additional structures are absent.

Although leaves vary dramatically in size and shape they are traditionally divided into two major morphogenetic classes. Some Types of Compound Leaves In the compound type of leaves the individual parts of the leaf blade are called leaflets and their leaf stalks the petiolules. In simple leaves the lateral bud of the simple leaf occurs at the base of the petiole while in compound leaves there are no lateral buds at the base of each leaflet.

Simple leaves have single leaf blade or lamina while compound leaves have smaller and separate leaf blades called leaflets. Compound leaves can be pinnate with an expanded rachis that bears leaflets or palmate with no rachis expan- sion Fig. Simple leaves have a single flat blade synonymous here with the lamina the margins of which are continuous and may be smooth entire lobed or serrated.

Guavas mangoes and numerous types of oaks contain the simple leaves on the flip side baobab neem rose and dessert cotton comprises the compound leaves. The term frond is also used to refer to the compound leaves of palm plants and ferns. Clover Chestnut Citrus Limon Buckeye Citrus maxima etc.

Compound leaves can be separated into palmate and pinnate leaf forms. The dissection or incision of a leaf depends on the type of venation. On a compound leaf you should expect a bud node at the base of each stempetiole but no.

The key difference between simple and compound leaves is that the leaf blade of the simple leave is undivided while the leaf blade of a compound leaf has several leaflets. To understand the difference between the simple and compound leaves let us know the incisions which are named as follows. As some simple leaves form on branches in.

More than one leaf blade per node axillary buds are at the node Linear Oval Round Triangular. This video is based on class 11th biology of NCERT book page no70 topic no. 5 LE VEIN Patterns Leaf Edges MNLA Handout for Lesson A2.

Difference Between Simple and Compound Leaves The difference primarily between simple and compound leaves is that in simple leaves there is a single leaf blade and depression that do not split the leaf blade whereas in compound leaves the depression is deep such that it splits the leaf blades into leaflets. Leaf is the most important photosynthetic structure in green plants. In pinnately compound leaves the incision progresses from the leaf margin to the midrib but in palmately compound leaves the incision progresses from the margin to the base of the leaves.

One leaf blade per node Compound Leaf. All leaves whether simple or compound will have a bud node at the place of petiole attachment to the twig. Core Difference between Simple and Compound Leaves In Point Form Simple leaves have a single leaf blade while compound leaves have several leaflets with smaller leaf blades.

Understanding leaves to help identify trees. Quadrifoliate trifoliate bifoliate and unifoliate palmate arrangements can be seen in compound leaves. Leaf Blade Simple leaves have a single leaf blade that is connected by a petiole to a twig.

In palmately compound leaves the leaflets grow from a single point of the petiole. Simple leaves have lateral buds at the petiole while compound leaves do not have lateral buds. Furthermore a simple leaf always contains a lateral bud at the base while a compound leaf has no lateral buds at the base of the leaflet.

The extension of the petiole bearing the leaflets is called the rachis. As the leaflet arrangement looks like the fingers of palm it is called palmate. Simple leaves consist of a single photo- synthetic lamina at a node and can sometimes be deeply lobed or dissected whereas compound leaves have many individual laminar units borne on a rachis that arises at a node.

The simple leaf has got all the structures of a typical leaf ie leaf blade leaf apex leaf-base leaf margin. Additionally there are bipinnate and tripinnate variations of compound leaves.
