Detailed explanation-1: -The lateral meristems or secondary meristems are found in all woody plants which consist of the vascular cambium and the cork cambium. They allow the growth of plant girth-wise making it bigger in size. This type of growth in vascular plants is called secondary growth. So, the correct answer is ‘Lateral meristem’.
Detailed explanation-2: -The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems. It is found in woody and many herbaceous dicots, gymnosperms and some monocots (monocots usually lack secondary growth).
Detailed explanation-3: -Cork cambium is the tissue seen in several vascular plants as a portion of the epidermis. Found between the cork and the primary phloem, it is one of the several layers of the bark. Cork cambium is the lateral meristem that is accountable for secondary growth substituting the epidermis in the roots and stems.
