The two types of vascular tissue in plants that transport energy and materials are:

* Xylem: This tissue transports water and dissolved minerals from the roots to the rest of the plant. It's like the plant's plumbing system.

* Phloem: This tissue transports sugars produced during photosynthesis from the leaves to other parts of the plant for growth, storage, and energy. It's like the plant's food delivery system.

So, while both xylem and phloem are involved in transporting essential materials within the plant, they have different roles and transport different substances.
