Detailed explanation-1: -Lateral meristem is responsible for the increase in the girth of the stem. It is found beneath the bark (called cork cambium) and in vascular bundles of dicot roots and stems (called vascular cambium) as thin layers. It is composed of such initials which divide mainly in one plane and increases the girth of the stem.
Detailed explanation-2: -Complete answer: The girth of the stem or root increases because of ‘Cambium’. Cambiums are the lateral meristems that participate in the secondary growth of dicots.
Detailed explanation-3: -Lateral meristems assist in increasing girth. These lateral meristems assist in the lateral growth of the plant, the growth in the thickness.
Detailed explanation-4: -Lateral meristems are referred to as the vascular cambium and cork cambium. Cell divisions in lateral meristems are responsible for increases in plant girth.
Detailed explanation-5: -Final Answer: The girth of the stem or root increases due to Cambium.
