Which plants have net veined leaves?
Fruit and deciduous trees, vegetable plants (not corn), most wildflowers, and many shrubs and flowers are examples of plants with netted veins. In leaves with parallel veins, major veins most commonly run parallel to each other the length of the leaf.
What are net vein leaves?
: having veins arranged in a fine network a net-veined leaf — see venation illustration — compare parallel-veined.
What are leaf veins?
Veins are composed of xylem and phloem cells embedded in parenchyma, sometimes sclerenchyma, and surrounded by bundle sheath cells. The vein xylem transports water from the petiole throughout the lamina mesophyll, and the phloem transports sugars out of the leaf to the rest of the plant.
What are netted veins?
Veins in a branch- ing pattern are called netted veins. A leaf with netted veins sometimes has several smaller veins branching out of a dominant midrib, a condition known as pinnately netted. Elms and oaks have pinnate netting. A leaf may sometimes have several dominant veins branching out from the petiole.
What are straight veined leaves?
The arrangement of veins in a leaf is called the venation pattern. Monocots have parallel venation in which the veins run in straight lines across the length of the leaf without converging. In dicots, however, the veins of the leaf have a net-like appearance, forming a pattern known as reticulate venation.
What does midrib mean?
: the central vein of a leaf.
What are veins in leaves called?
A leaf is often organized with one main vein running down the middle of the blade. 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.
What is the arrangement of veins in a leaf called?
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.
Where does netted venation occur in a plant?
Netted venation is a form of leaf venation composed of veins arranged in a net-like pattern. The veins branch from the major midribs and split into smaller stands of veinlets, which subsequently unite to form a composite network. Netted venation occurs in the leaves of almost all dicotyledonous angiosperms.
Where are the veins in a pinnate plant?
In pinnate venation, the veins extend crossing the midrib to the circumference, as seen in apple, mango, peepul, guava, cherry and peach plants. Pinnate venation typically shows one vein more outstandingly than the others, and consists of veins that run from the base of the leaf blade to its tip in a central longitudinal arrangement.
Why are the leaves on a dicot plant net veined?
Leaves with stomata only on the lower side are known as hypostomatous leaves. This arrangement of stomata allows dicot leaves to conserve water. Dicot leaves (and a small number of atypical, “net-veined” monocot leaves) have two different types of mesophyll: palisade mesophyll and spongy mesophyll.
