Detailed explanation-1: -The meristem that lies on the lateral side of the cambium is known as a lateral meristem. Lateral meristem increases the thickness of the plant body which is also known as secondary growth of plants.

Detailed explanation-2: -Vascular cambium and cork cambium, also called secondary meristem, are responsible for secondary growth in plants.

Detailed explanation-3: -Lateral meristems facilitate growth in thickness or girth in a maturing plant. Intercalary (also called basal) meristems occur only in some monocots, at the bases of leaf blades and at nodes (the areas where leaves attach to a stem).

Detailed explanation-5: -Lateral Meristems are observed in stems and roots of the plant body. Lateral meristem stimulates the increase in the girth of stem and root. It increases the lateral thickness of the plant stem and root. Hence, lateral meristem helps in increasing the girth.
