Cambium (botany)

A cambium (plural cambia or cambiums), in botany, is a tissue layer that provides undifferentiated cells for plant growth. It forms parallel rows of cells, which result in secondary tissues.^[1]

There are several distinct kinds of cambium found in plant stems and roots:

• Cork cambium, a tissue found in many vascular plants as part of the periderm.
• Unifacial cambium, which produces cells to the interior of its cylinder.
• Vascular cambium, a lateral meristem in the vascular tissue of plants.
