Definitions:

Vascular Cambium

A layer of plant tissue located between the xylem and the phloem in the stems and roots of vascular plants, responsible for secondary growth and producing new transport cells.

Sclerenchyma

Sclerenchyma is a type of plant tissue characterized by thick, lignified cell walls that provide support and strength to the plant structure.

Annual Rings

Annual rings are layers of growth found in the cross-section of tree trunks, representing one year of growth, and can be used to estimate the age of a tree.

Summer Rings

Annual growth rings found in trees in temperate zones that are typically larger and lighter in color, reflecting faster growth during the summer months.
