1 dzień temu · The two tissue types that make up plant veins are called the xylem and phloem. The vascular system in plants is made up of two tissue types: xylem and phloem. These tissues are responsible for transporting fluids and nutrients throughout the plant, similar to the role of blood in animals. Xylem is a vascular tissue that transports water and ...
18 kwi 2013 · We synthesize classical concepts and the recent literature on a wide range of aspects of leaf venation. We describe 10 major structural features that contribute to multiple key functions, and scale up to leaf and plant performance.
Leaf veins are vascular bundles coming to the leaf from stem. The arrangement of veins in a leaf is called the venation pattern. Frequently, there is one or more main vein (primary vein) and secondary veins that branch from it. Tertiary veins branch from secondary veins (F igure \(\PageIndex{11}\)). Figure \(\PageIndex{11}\): The main (primary ...
Within each leaf, the vascular tissue forms veins. The arrangement of veins in a leaf is called the venation pattern. Monocots and dicots differ in their patterns of venation (Figure 23.22). Monocots have parallel venation; the veins run in straight lines across the length of the leaf without converging at a point.
The arrangement of veins in a leaf is called the venation pattern. Monocots and dicots differ in their patterns of venation ( Figure 30.22 ). Monocots have parallel venation; the veins run in straight lines across the length of the leaf without converging at a point.

The smaller lateral veins of the leaf are initiated near the leaf tip; subsequent major lateral veins are initiated sequentially toward the base, following the overall pattern of leaf development. A major lateral vein may have one or more orders of smaller veins, which also are initiated in… Read More.
