Secondary xylem
It is located in the vascular bundles between the primary xylem (wood) and primary phloem (bast) tissues.
It is located in the vascular bundles between the primary xylem (wood) and primary phloem (bast) tissues.
Wood consists mostly of xylem cells, along with some cambium cells and phloem cells that appear as the 'growth rings' in wood cross-sections.
Primary growth is responsible for elongating the plant. In woody plants, primary growth is then followed by secondary growth which allows the plant stem to increase in thickness or girth.
Secondary xylem
phellem(cork), phellogen(cork cambium), phelloderm(secondary cortex), primary phloem and secondary phloem constitutes BARK
Trees have two types of growth: primary growth and secondary growth. · Primary growth occurs at the tips of roots and stems and results in their growing taller or longer. · Secondary growth takes place in the vascular cambium and the cork cambium and results in an increase in the diameter of the stem or trunk of the tree. Cambium lies between the old wood and the bark of the tree. The vascular cambium is a thin layer cells that produces conducting cells - xylem and phloem. · The phloem is the outer layer, and is sometimes referred to as the inner bark. It is a food conducting tissue. The xylem is located toward the inside of the cambium layer. · The xylem is the vascular tissue through which most of the water and minerals of the tree are conducted. More secondary xylem (added toward the inside of the cambium layer) than secondary phloem (added toward the outside of the cambium layer) is produced by the cambium. The definition of wood is secondary xylem, reflected by the origin of the term 'xylem', the Greek word xylon, for wood. Another layer, the cork cambium, contributes to the expanding girth of a tree. The cork cambium is a thin layer cells that ultimately produces the bark of the tree. The bark is composed of several types of tissue produced (both toward the inside and the outside of the tree) by the cork cambium layer.

Secondary Xylem
hey sorry if i am wrong but i think the heartwood of a tree of the very middle section followed by the xylem -> cambium -> phloem -> them the bark
Examples of primary fuels - wood, coal Examples of secondary fuels - charcoal, coke
bark and core-wood
secondary xylem
C. secondary xylemI'm positive its c. secondary xylem
