vascular cambium
The growth of tissue that produces phloem and xylem in the stems of woody plants is called vascular cambium. It is a lateral meristem that produces secondary xylem (wood) towards the inside of the stem and secondary phloem towards the outside, allowing for the thickening and expansion of the stem over time.
Secondary growth, carried out by the vascular cambium, increases the girth of stems and roots. This process involves the production of secondary xylem towards the inside and secondary phloem towards the outside of the plant. The continuous activity of the vascular cambium results in the thickening of stems and roots over time.
The tissue you are referring to is called vascular cambium. Vascular cambium is a meristematic tissue that is responsible for secondary growth in plants, producing additional xylem towards the inside and phloem towards the outside, contributing to the increase in girth of woody plants.
Most of the plant's new xylem and phloem are produced in the vascular cambium, which is a thin layer of meristematic cells located between the xylem and phloem in the stem and root. This region is responsible for secondary growth in plants, leading to the production of new xylem towards the inside and new phloem towards the outside.
In a mature dicot stem, the bark is composed of several tissue layers including the cork cambium (phellogen), cork cells (phellem), phelloderm, secondary phloem, and sometimes remnants of primary phloem and cortex tissues. The cork cambium produces the cork cells on the outside and the phelloderm on the inside, providing protection and structural support.

The secondary meristem responsible for producing wood toward the inside and bark toward the outside of a tree is called the cambium. Specifically, the vascular cambium is a layer of meristematic tissue that generates secondary xylem (wood) inward and secondary phloem (bark) outward. This process contributes to the growth in diameter of the tree trunk and enhances its structural support.

The secondary meristem responsible for producing wood toward the inside and bark toward the outside of a tree is called the cambium. Specifically, the vascular cambium generates new xylem (wood) on the inner side and new phloem (bark) on the outer side. This growth contributes to the tree's increase in diameter over time.
