AP BIOLOGY

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: -Vascular tissue in plants is made of two specialized conducting tissues: xylem, which conducts water, and phloem, which conducts sugars and other organic compounds. A single vascular bundle always contains both xylem and phloem tissues.

Detailed explanation-3: -The vascular system consists of two conducting tissues, xylem and phloem; the former conducts water and the latter the products of photosynthesis.

Detailed explanation-4: -Xylem consists of tracheids, vessels, parenchyma, and fibers.

Detailed explanation-5: -The ferns, gymnosperms, and flowering plants are all vascular plants. Because they possess vascular tissues, these plants have true stems, leaves, and roots.
