Heartwood, Xylem, cambium, phloem, bark/outside layer
The six layers of a young woody stem, from outermost to innermost, are the bark, cork cambium, cork, secondary phloem, vascular cambium, and secondary xylem. These layers provide structural support, transport nutrients and water, and protect the inner tissues of the stem.
The outermost layer of ground tissue in a stem is called the cortex. It helps protect the inner layers of the stem and provides structural support.
Stem cells in the early embryo start differentiating to form the three primary germ layers - ectoderm, mesoderm, and endoderm. These layers give rise to all the tissues and organs in the body.
The layers of tissue within a woody stem, from the center to the outermost layer, are as follows: the pith, which is the central storage tissue; the xylem, responsible for water and nutrient transport; the cambium, a layer of actively dividing cells that facilitate growth; the phloem, which transports sugars; and finally, the bark, the protective outer layer.
The layers of tissue in a woody stem, from the outermost to the innermost, are: the bark (which includes the protective outer layer and the phloem), the cambium (a thin layer of actively dividing cells), the xylem (which consists of heartwood and sapwood), and the pith at the center. The bark serves to protect the stem, the cambium is responsible for secondary growth, the xylem conducts water and nutrients, and the pith stores nutrients.

A stem cell that can differentiate into any cell (tissue) of the three germ layers.
Stem cells in the early embryo start differentiating to form the three primary germ layers - ectoderm, mesoderm, and endoderm. These layers give rise to all the tissues and organs in the body.
The rough outer layer of the woody stem is called bark. Bark acts as a protective barrier for the inner layers of the stem, helping to prevent damage from physical elements and pathogens.

Pine trees have a woody stem. The stem of a pine tree is characterized by its strong, sturdy structure, which allows the tree to support its height and weight. The woody stem is composed of layers of xylem and phloem tissues that provide structural support and transport water, nutrients, and sugars throughout the tree.
Cambium, in plants can be defined as layers of actively dividing cells between xylem (wood) and phloem (bast) tissues that is responsible for the secondary growth of stems and roots. Secondary growth can be defined as occurring after the first season and results in increase in thickness
The type of stem cell that can develop into any cell in the human body or the placenta is called a pluripotent stem cell. These cells have the ability to differentiate into all three primary germ layers: ectoderm, mesoderm, and endoderm, which give rise to various tissues and organs. Embryonic stem cells are the most well-known example of pluripotent stem cells, as they are derived from the inner cell mass of a blastocyst.
Pluripotent stem cells can differentiate into the most types of cells. They have the ability to develop into nearly all cell types within the three germ layers: ectoderm, mesoderm, and endoderm. In contrast, multipotent stem cells are more limited, typically differentiating into a narrower range of cell types within a specific tissue or organ. Embryonic stem cells, a type of pluripotent stem cell, are particularly noted for their extensive differentiation potential.
