Question

Write a short note on a vascular bundle.

Answer 1

Hint: The procambium of the growing stem gives rise to the vascular bundles. Vascular bundles are found in complex arrangements throughout the stem of monocotyledons.

Complete answer:
In vascular plants, the avascular bundle is a component of the transport system. The transport takes place in the stem, which comes in two varieties: xylem and phloem. Both of these issues are found in a vascular bundle, which also contains supporting and protective tissues.
The xylem is usually located axially, while the phloem is located abaxially. This means that the xylem is closer to the center of the stem or root, while the phloem is closer to the outside. The adaxial surface of a leaf is usually on the upper side, while the abaxial surface is on the lower side.
This is why aphids are typically found on the underside of a leaf rather than the top because the sugars produced by the plant are transported by the phloem, which is closer to the lower surface.
The vascular bundles are organized in three layers and develop unequally at each level. The main vascular bundles alternate with air canals and are embedded in chlorenchyma, forming a single conspicuous abaxial arc.

Note:
Vascular tissue is made up of the plant's main transport systems, xylem, and phloem. They are found in vascular bundles throughout all plant organs, traversing roots, stems, and leaves. Xylem is in charge of transporting water and dissolved ions from the roots up through the plant.
