Leaves, stems, roots, and flowers are all made up of various tissues.

Let's now look at some specialized types of vascular tissue found in plant stems that is surrounded by the ground tissue. Previously, the concept of vascular tissue was addressed. Remember that vascular tissue is the tissue used to transport water and nutrients throughout a plant.It acts like roads and plumbing, moving around nutrients and water needed by the plant. There are two types of vascular tissue: xylem and phloem.Xylem transports water and dissolved minerals, while phloem transports food. Previously it was pointed out that an easy way to remember which vascular tissue is which is that 'phloem' and 'food' both start with the same sound.et's now look at some specialized types of vascular tissue found in plant stems that is surrounded by the ground tissue.
