**Cambial tissue** is the tissue that produces new cells. It contains stem cells that can transform into any type of cell in the body. For example, muscle cells are formed from cambial muscle tissue, and bone cells are formed from bone tissue. Cambial cells lie next to mature cells and are just waiting for a signal to start producing their counterparts. There are three types of cambial tissues:
- Pulp - inside the leaf. Consists of non-intertwined leaves and internodes. There are no cambial features in the cells of the pulp structure. This is the most common type of cambial cell. - Vital – core with a mesh plate. Life tissue is formed by the peripheral layers of phloem. Young meristematic cells have an enlarged nucleus and a fine network in the plates. - Phloematic - with cambial folds. Plants containing phloem tissue have developed phloem layers. At
