BOTANY

Detailed explanation-1: -Cell division by the cambium produces cells that become secondary xylem and phloem. As secondary phloem and xylem tissue accumulates, it both increases the girth of the stem and forms wood and bark.

Detailed explanation-2: -cambium, plural Cambiums, orCambia, in plants, layer of actively dividing cells between xylem (wood) and phloem (bast) tissues that is responsible for the secondary growth of stems and roots (secondary growth occurs after the first season and results in increase in thickness).

Detailed explanation-3: -Fascicular cambium is the vascular cambium present in the vascular bundle. This cambium is present between the primary xylem and primary phloem and separates them from each other.

Detailed explanation-4: -Cambium. The vascular bundles of dicot stems contain a layer of meristem cells, called the cambium (or vascular cambium), located between the xylem and phloem. See it in 3D! Function: These cells facilitate secondary growth, dividing to create new xylem and phloem cells, and thus widening the girth of the stem.

Detailed explanation-5: -When xylem and phloem within a vascular bundle are arranged in an alternate manner along the different radii, the arrangement is called radial such as in roots.
