Detailed explanation-1: -Secondary, or lateral, meristems, which are found in all woody plants and in some herbaceous ones, consist of the vascular cambium and the cork cambium. They produce secondary tissues from a ring of vascular cambium in stems and roots.

Detailed explanation-2: -Lateral meristems are referred to as the vascular cambium and cork cambium. Cell divisions in lateral meristems are responsible for increases in plant girth. Ordered cell divisions along vascular initials are required for organization of lateral meristems.

Detailed explanation-3: -The vascular cambium is composed of two kinds of cells, ray initials and fusiform initials. In cross section these look very similar. Both are small, flattened cells with thin walls.

Detailed explanation-4: -In woody roots the vascular cambium (the lateral meristem that gives rise to secondary phloem and secondary xylem) originates in the pericycle as well as in the procambium; the procambium is the primary meristematic tissue between the primary phloem and xylem.

Detailed explanation-5: -Lateral meristems are a form of meristematic tissue connected with side growth. They are made up of meristematic cells located in a plant’s lateral parts.
