The vascular tissue is present in Roots, Stems and leaves. In Roots the xylem is present pericycle where as in shoots those are present in vacular bundles, and in leaves it is present in veins.

3. The answer is

The cell types or elements in the xylem is Tracheids, vessel elements, xylem parenchyma and xylem sclerenchyma

4. The answer is

The cell types or elements in the phloem is Sieve tubes, companion cells, phloem parenchyma, bast fibers and intermediary cells
