Explanation:
The diagram is a cross section of stem of a dicot plant, specifically <em>Hypericum perforatum</em>. It shows all the structures present in the stem like xylem, phloem, pith, cortex etc. The structure labelled X is phloem. It is present between xylem (stained red) and peripheral cortex. Phloem is responsible for conduction of sugars and nutrients in the plant thus it carries the food produced by leaves. Together xylem and phloem make the vascular tissue which surrounds the central pith (stained bluish-green).
