Detailed explanation-1: -Vascular tissue is comprised of the xylem and the phloem, the main transport systems of plants. They typically occur together in vascular bundles in all plant organs, traversing roots, stems, and leaves. Xylem is responsible for the transport of water and dissolved ions from the roots upwards through the plant.

Detailed explanation-2: -Xylem and phloem are called vascular or conducting tissues because both xylem and phloem tissues transport materials in plants, they are together called vascular tissues.

Detailed explanation-3: -Xylem is a principal component of vascular tissue, together with phloem and cambium. Its main roles are transporting water and solutes originating from the plant–soil interface to the stems and leaves, and providing mechanical support and storage.

Detailed explanation-4: -The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally. There are also two meristems associated with vascular tissue: the vascular cambium and the cork cambium.

Detailed explanation-5: -So, the correct answer is ‘conjoint’
