Key Concepts

Vascular Cambium

A layer of meristematic cells in woody plants that is responsible for secondary growth by producing new layers of vascular tissue. It is situated between the secondary xylem and secondary phloem, where it contributes to the thickening of stems and roots over time.

Secondary Growth

The process in plants where growth occurs in thickness rather than length. This is facilitated by lateral meristems such as the vascular cambium, which adds structural support and enhances the plant’s capacity for water and nutrient transport.

Xylem

A type of vascular tissue primarily responsible for conducting water and dissolved minerals from the roots to the rest of the plant. In the context of secondary growth, the secondary xylem forms the bulk of the woody tissue inside a stem.

Phloem

A vascular tissue tasked with the transport of sugars, nutrients, and metabolic signals throughout the plant. During secondary growth, the secondary phloem is produced by the vascular cambium and is located adjacent to the secondary xylem.
