Detailed explanation-1: -Cambium is situated below the bark which constitutes the lateral meristem and is responsible for the increase in the diameter of the stem.

Detailed explanation-2: -The vascular cambium is responsible for increasing the diameter of stems and roots and for forming woody tissue. The cork cambium produces some of the bark. In dicot stems, the vascular cambium initially differentiates from procambial cells within the vascular bundles (Fig. 1.8A).

Detailed explanation-3: -Secondary meristems, or lateral meristems, are responsible for secondary growth. It can increase the girth and thickness of the stem. Meristems are responsible for wound healing because they regenerate from other cells in wounded tissues.

Detailed explanation-4: -The increase in diameter of a plant’s stem and root is caused by cork cambium and vascular cambium. They can be found in dicot plants. These are the lateral meristems, which are in charge of the plant’s secondary growth.

Detailed explanation-5: -Lateral meristems are the type of meristems known as the cambium and cork cambium are arranged parallel to the sides of an organ and It divides only periclinally or radially and is responsible for increase in girth or diameter and hence cause secondary growth.
