CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -The vascular cambium is responsible for increasing the diameter of stems and roots and for forming woody tissue. The cork cambium produces some of the bark. In dicot stems, the vascular cambium initially differentiates from procambial cells within the vascular bundles (Fig.

Detailed explanation-2: -The cambium produces new layers of phloem on the outside and of xylem on the inside, thus increasing the diameter of the stem. In woody plants, this process produces wood and shapes the plant into a tree with a thickened trunk.

Detailed explanation-3: -The lateral meristem is responsible for the plants’ thickness.

Detailed explanation-4: -The inner soft bark, or bast, is produced by the vascular cambium; it consists of secondary phloem tissue whose innermost layer conveys food from the leaves to the rest of the plant.
