Typically, vascular tissue is organized as ______ in stems and as _____ in roots.
Concept introduction: Vascular bundle is a part of transport system in vascular plants. Xylem and phloem are the two tissues present in the vascular bundles. In addition to this, supporting and protective tissues are also present in the vascular tissue. The vascular tissues in the stems are called vascular bundle and the vascular tissue in the roots are called vascular cylinder. The vascular tissue structure varies in both monocot and eudicot plants.
Reasons for the correct statement:
The xylem and phloem are organized as long, multi-stranded vascular bundles in the stem. These bundles run lengthwise through the stem. In the roots, the vascular tissue is organized within a single central vascular cylinder. The vascular cylinder consists of the pericycle, vascular tissues, and the supporting cells.
Option a. is given as, āmultiple vascular bundles; one vascular cylinderā. As the vascular tissue in the stem has multiple vascular bundles and the roots have one vascular cylinder, option a. is correct.
Reasons for the incorrect statements:
Option b. is given as, āone vascular bundle; multiple vascular cylindersā.
In plants, the stems have multiple vascular bundles and roots have single vascular cylinder...
