Question: 1 / 400

Which of the following is not a part of the tree's vascular system?

Xylem

Phloem

Roots

The roots are not part of the tree's vascular system, as they primarily function in the uptake of water and nutrients from the soil and serve to anchor the tree in place. The vascular system consists of specialized tissues that are responsible for the transportation of water, nutrients, and food within the tree.

Xylem is a critical component of this vascular system, responsible for transporting water and dissolved minerals from the roots to the rest of the tree. Phloem complements this by transporting the products of photosynthesis, mainly sugars, from the leaves to other parts of the plant. Cambium, a layer of tissue between xylem and phloem, is involved in the growth and development of these vascular tissues.

In summary, the roots have a different physiological role and are not categorized within the vascular components that facilitate the transport of essential substances throughout the tree.
