tree ring is to secondary growth.

secondary growth is to width.

|
|
vascular cambium is to secondary growth.

Detailed explanation-1: -Primary growth is controlled by root apical meristems or shoot apical meristems, while secondary growth is controlled by the two lateral meristems, called the vascular cambium and the cork cambium. Not all plants exhibit secondary growth.
Detailed explanation-2: -Vascular cambium and cork cambium, also called secondary meristem, are responsible for secondary growth in plants. They increase the thickness of the plant body.
Detailed explanation-3: -It is the result of cell division in the shoot apical meristem. Secondary growth is characterized by an increase in thickness or girth of the plant. It is caused by cell division in the lateral meristem. Herbaceous plants mostly undergo primary growth, with little secondary growth or increase in thickness.
Detailed explanation-4: -In many vascular plants, secondary growth is the result of the activity of the two lateral meristems, the cork cambium and vascular cambium. Arising from lateral meristems, secondary growth increases the width of the plant root or stem, rather than its length.
