Question

Name the tissue which replaces the primary epidermis of the stem on secondary growth.

Answer 1

Answer:

Secondary growth adds to the diameter of a stem or root; vascular cambium adds xylem (inward) and phloem (outward), and cork cambium replaces epidermis with bark.

Answer 2

The answer to this question is periderm. Periderm comes from cambium or as it is called as cork cambium, which forms the outer hard bark of the tree.

The periderm eliminates the primary outer membrane of the plant cell which is epiderm and takes its place by completely destroying it and making the outer covering of the plant hard and rough and scaly.
