vein
Quick Summary
In plants, veins are essentially vascular bundles, which are crucial components of the vascular system. These bundles are composed of xylem and phloem. Xylem transports water and minerals from the roots to the leaves, while phloem carries food produced during photosynthesis from the leaves to other parts of the plant. In leaves, these veins form a network that distributes these vital substances throughout the leaf structure. The pattern of these veins, known as venation, can vary, with common types including netlike patterns in dicots and parallel patterns in monocots.12345

leafLeaf morphology…type of venation (arrangement of veins). When only a single blade is inserted directly on the petiole, the leaf is called simple. The margins of simple leaves may be entire and smooth or they may be lobed in various ways. The coarse teeth of dentate margins project at right angles,…
