In some plants we can see lateral small-leaf like structure at the leafbase.When the leaf is a bud stipules protect the bud as a cover.Later ,it changes into thorns or stay without change.
a small paired usually leaf like outgrowth occurring at the base of a leaf or its stalk
these are the leafy structures that protect the young leaves :)
tignan niyo lang yung dahon makikita niyo na yung stipules dun.....
Modified leaf or stipules
Leaf tendrils originate either from stipules or leaflets whereas the stem tendrils are modification of axillary buds representing the stem branches.
A Neem leaf is a compound leaf a
it is a simple leaf.

Modified leaf or stipules
Each leaf typically has a leaf blade ( lamina ), stipules, a midrib, and a margin. Some leaves have a petiole, which attaches the leaf to the stem; leaves that do not have petioles are directly attached to the plant stem and are called sessile leaves.
Leaf tendrils originate either from stipules or leaflets whereas the stem tendrils are modification of axillary buds representing the stem branches.
In botany, stipule (Latin stipula: straw, stalk[1]) is a term coined by Linnaeus[1] which refers to outgrowths borne on either side (sometimes just one side) of the base of a leafstalk (the petiole). A pair of stipules is considered part of the anatomy of the leaf of a typical flowering plant, although in many species the stipules are inconspicuous or entirely absent (and the leaf is then termedexstipulate).In some older botanical writing, the term "stipule" was used more generally to refer to any small leaves or leaf-parts, notably prophylls.Stipules are morphologically variable and might appear as glands, scales, hairs, spines, or laminar (leaf-like) structures. A relationship exists between the anatomy of the stem node and the presence or absence of stipules. Most plants with trilacunarnodes have stipules; species with unilacunar nodes lack stipules (Sinnott and Bailey, 1914, cited in Esau, 1953).By. fan of Chicser ( GEllo )
The shape of the maple leaf is a 3 point leaf facing upward. 1 pointing left up 1 pointing straight and one pointing up right
what is the function of each of the following external parts of a leaf?
Typically a leaf is a thin, dorsiventrally flattened organ, borne above ground and, Furthermore, several kinds of leaf-like structures found in vascular plants are not totally. The internal organisation of most kinds of leaves has evolved to maximise of a petiole (leaf stalk), a lamina (leaf blade), and stipules.
In some plants we can see lateral small-leaf like structure at the leafbase.When the leaf is a bud stipules protect the bud as a cover.Later ,it changes into thorns or stay without change. There aren't any obvious functions of the stipule. It may have been involved in protecting emerging leaves. Some stipules appear to protect the buds. Stipular spines may serve as protection for the plant by keeping it from being eaten. Sipular spines in some plants serve as a home for ants.
Leaves are made up of a stem (petiole), a leaf blade (lamina) and stipules which attach at the base of the stem. Leaves contain an epidermis that covers the surface of the leaf, a mesophyll (located inside the leaf that is the primary location for photosynthesis in the plant), and an assortment of veins that run through the mesophyll. The veins are made up of xylems (tubes that bring water and minerals from the roots of a plant to the leaf) and phloems (tubes that move sap produced by phtosynthesis out of the leaf)
holds the leaf in connects to the plantpetiole is the thin green sructure that connects the main stem to a leaf.its also called MESOPODIUM.its main function is to direct the leaf from the branch so that it could get sufficient sunlight to perform photosynthesis
as a leaf is a leaf?! /
