The vascular cambium is a lateral meristem, meaning it's responsible for growth in width, not length. It produces two types of vascular tissues:

* Secondary xylem: This is the wood of the plant. It's responsible for transporting water and dissolved minerals upwards from the roots.

* Secondary phloem: This tissue transports sugars and other organic compounds produced by photosynthesis throughout the plant.

So, the active cell division of the vascular cambium directly gives rise to secondary xylem and secondary phloem. These tissues are what make up the bulk of a woody plant's stem and roots.
