Detailed explanation-1: -The lateral meristem tissues are responsible for the secondary growth of plants. The secondary growth of plants increase in stem thickness and it is due to the activity of the lateral meristems, which are absent in herbs or herbaceous plants.

Detailed explanation-2: -In many vascular plants, secondary growth is the result of the activity of the two lateral meristems, the cork cambium and vascular cambium. Arising from lateral meristems, secondary growth increases the width of the plant root or stem, rather than its length.

Detailed explanation-3: -The process of secondary growth is controlled by the lateral meristems, and is similar in both stems and roots. Lateral meristems include the vascular cambium and, in woody plants, the cork cambium (cambium is another term for meristem).

Detailed explanation-4: -Occurrence of secondary growth due to the activity of two laterally positioned meristems, viz. the vascular cambium and the phellogen (cork cambium) is a common feature of the gymnosperms and dicotyledons.

Detailed explanation-5: -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.
