OBJECTIVE FORESTRY

Detailed explanation-1: -Note: Bark forms the thinner parts than the woody tissues of the stem. Both outer and inner bark is formed by the vascular cambium. The outer bark contains secondary xylem whereas the inner bark contains secondary phloem. The inner bark accumulates dead tissues and the outer bark sloughs off dead tissues.

Detailed explanation-2: -Bark is not the same thing as periderm. Bark is all the tissues outside the vascular cambium, i.e. secondary phloem, any primary tissues that are still there, periderm, and dead tissue outside the periderm. Composed of an inner living part and an outer dead part.
