Leaf structure is described by several terms that include: Being one of the more visible features, leaf shape is commonly used for plant identification. Similar terms are used for other plant parts, such as petals, tepals, and bracts. Shaped like a lyre, pinnately lobed leaf with an enlarged terminal lobe and smaller lateral lobes.

A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, [1] usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", [2][3] while the leaves, stem, flower, and …

Leaves are generally composed of a few main parts: the blade and the petiole. Figure 13.1.2 13.1. 2: A leaf is usually composed of a blade and a petiole. The blade is most frequently the flat, photosynthetic part. The petiole is a stem that attaches the …

Let us learn about Diversity in the Leaf. After reading this article you will learn about: 1. Definition of a Leaf 2. Parts of a Leaf 3. Types. Definition of a Leaf: The leaf is a flattened, lateral outgrowth of the stem in the branch, developing from a node and having a bud in its axil.

Feb 2, 2023 · A typical leaf shows three main parts: 1) petiole, 2) leaf base, and 3) leaf blade or lamina, each performing specific functions. 1. Petiole. It is the stalk that connects a leaf to the stem of the plant, it is made of complex conducting tissues called vascular tissues. Functions. 2. …

Aug 19, 2017 · The term leaf refers to the organ that forms the main lateral appendage on the stem of vascular plants. In general, leaves are thin, flat organs responsible for the photosynthesis of the plant. Although photosynthesis typically only occurs on the upper surface of the leaf, it can occur on both sides in some plant species.

Leaves are the chief organs of photosynthesis. The green leaves of the plant are collectively called as foliage of the plant. The three main parts of a typical leaf are 1. Leaf base 2. Petiole 3. Lamina. Leaf. Leaves are green, thin flattened lateral outgrowths of the stem. They are borne at the nodes of the stem.

Jul 27, 2022 · Leaves are shoot structures that attach to stems and branches at nodes. Leaves are made up of cells that usually contain a high concentration of chloroplasts (cell organelles unique to plants) and are specialized sites for photosynthesis.

May 18, 2024 · Features of a leaf (i.e., characters help to distinguish it) include having a bud in the axil, not growing by apex, not producing new leaves or shoots, and having hierarchal morphology (see below).

Leaf is a green, dissimilar exogenous lateral flattened outgrowth which is borne on the node of a stem or its branch and is specialised to perform photosynthesis. Typically it is a thin expanded green structure which bears a bud in its axil. The green colour of the leaf is due to the presence of chlorophyll. Leaves are arranged in acropetal order.
