CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Cork cambium (pl. cambia or cambiums) is a tissue found in many vascular plants as a part of the epidermis. It is one of the many layers of bark, between the cork and primary phloem. The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems.

Detailed explanation-3: -It lies just inside the endodermis. It is the outermost part of the stele of plants. The plants that undergo secondary growth, the pericycle contributes to the vascular cambium that often diverges into a cork cambium. So, the correct option is B-‘Dedifferentiated collenchyma cells of cortex’.

Detailed explanation-4: -The cambium present between primary xylem and primary phloem is called the intrafascicular cambium (within vascular bundles).

Detailed explanation-5: -Cork cambium forms cork on the outer side and secondary cortex on the inner side by giving off new cells on both sides. The layer of cells which is cut by cork cambium on the outer side ultimately becomes several layered thick cork (bark) of trees.
