pls answer the question name the type of leaf
Answers
Answer:
There are three main parts of a leaf – Leaf base, leaf lamina, and petiole. 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.

Leaves: Morphology, Types & Modification
Plants are an essential part of the ecosystem. Every life on the earth is directly or indirectly dependent on plants. Among the different parts of a plant, the leaf is the most essential.
Primarily, leaves have two functions: photosynthesis and transpiration. In some plants, it takes up the responsibility of reproduction also.

Let’s learn more about the morphology of leaves, parts of a leaf, different types of leaves and their modifications.
Structure of a Leaf
Leaves are thin, flat organs responsible for photosynthesis in the plants. It develops laterally at the node. It is an important part of the shoot system and it originates from shoot apical meristems.
The structure of a leaf is described below in detail :
Parts of a Leaf
Generally, leaf base, petiole, and lamina, together form the main parts of a leaf.
Leaf Base: This is the part where a leaf attaches to the stem. Leaf base has two small leaf-like structure called stipules. In plants like paddy, wheat, and other monocotyledons, this leaf base is wide and masks the stem.
Petiole: Petiole is the long, thin, stalk that links the leaf blade to the stem.
Lamina: Also known as leaf blade. It is the green, flat surface of the leaves. It consists of a small branched vein and veinlets. The vein that runs along the middle of the lamina is called midrib. Midrib divides the surface of the lamina into two. These veins and veinlets give rigidity to the leaf blade and help in the transportation of water and other substances.

Venation
Venation is defined as the arrangement of veins and the veinlets in the leaves. Different plants show different types of venation. Generally, there are two types of venation:
Reticulate venation: In a reticulate venation, the veinlets are randomly arranged and form a complex network of veinlets. Ex: Dicotyledonous plants like a rose plant.

Reticulate venation
Parallel venation: In a parallel venation, the veinlets run parallel to each other. Ex: In monocotyledons like paddy.

Types of Leaves
There are two broad categories of leaves – simple and compound, which are further classified into different groups based on their shape, size, their arrangements on the stem, leaves of flowering and non-flowering plants, and various other physical attributes.
The two different types of leaves found in a plant are:
Simple Leaf
When a single lamina is connected to the main stem by a petiole, the leaf is said to be simple. A simple leaf may be incised to any depth but not down to the midrib or petiole. Eg., Guava leaves
Compound Leaf
A compound leaf is a leaf made up of two or more leaflets. In a compound leaf, the midrib of the leaf is branched into different leaflets and is connected by a single petiole. For eg., Pea, palm leaves.
