Definition - What does Vascular System mean?
The vascular system of a plant is the tissue and series of tubes and veins that move nutrients collected by the roots to the stem and leaves.
A plant's vascular system is absolutely essential for the life of a plant, as nutrients wouldn’t move any further than the roots without it.
MaximumYield explains Vascular System
The vascular system runs up the stems or in the inner bark of trees to move nutrients upward in order to support the leaves. It’s a complex series of veins that extend throughout the plant, leave stems, and into the leaves themselves.
Monocots or grasses consist of scattered vascular bundles while dicots, which are more complex plants, have continuous vascular systems surrounding their central paths.
In trees, the central path of the vascular system runs through the inner bark and that’s why girdling or stripping of a ring of bark will cut off the flow of nutrients and ultimately kill the tree.
In some perennials, the vascular system may include the entire stem, but in most cases it does not and rather runs along the inside of the outer epidermal layer.
