What is the appropriate order of tissues in dicots moving from the bark to the pith?

In a dicot plant, the correct order of tissues moving from the bark to the pith is indeed cork cambium, phloem, cambium, and xylem.

Starting from the outer layer, the cork cambium is responsible for producing cork cells, which form the protective outer bark. Beneath the cork, the phloem is present. This tissue is crucial for the transport of nutrients, particularly sugars produced during photosynthesis, from the leaves to other parts of the plant.

The cambium, or vascular cambium, is located just inside the phloem and is a type of meristematic tissue that divides to form new phloem and xylem cells, thus contributing to the plant's growth in diameter. Finally, the xylem is found inward of the cambium and is responsible for transporting water and minerals from the roots to the rest of the plant. It also provides structural support.

This order reflects the organization of tissues in dicots, highlighting the roles of each layer in terms of growth, transport, and protection. Understanding this arrangement is fundamental to the study of plant anatomy and physiology, particularly for those involved in arboriculture and related fields.
