Final answer:

Secondary meristematic tissue involves vascular cambium, which produces wood and vascular tissues, and cork cambium, which generates bark.

Step-by-step explanation:

The type of meristematic tissue that has vascular cambium making wood and vascular tissues and cork cambium making bark is known as secondary meristematic tissue. The vascular cambium is responsible for the production of secondary xylem and phloem, which contributes to the growth in diameter or girth of the plant. This process is a part of what we know as secondary growth, which is exclusive to woody plants. Conversely, the cork cambium, another type of lateral meristem, generates cork cells that eventually form the bark of the tree. This cork layer contains a waxy substance called suberin that helps to repel water and protect the plant from external damage, while also reducing water loss.

Together with phelloderm, the cork cambium and cork cells form the periderm, replacing the epidermal layer of mature plants. It's important to note that in some plants, the periderm has tiny openings called lenticels that allow for the exchange of gases with the exterior environment, providing oxygen to living, metabolically active cells.
