Final answer:
The epidermis in plants is derived from the primary meristem known as the protoderm, which is differentiated from apical meristems.
Step-by-step explanation:
The epidermis is derived from a primary meristem called the protoderm. Apical meristems differentiate into three types of primary meristem tissue: the protoderm, which gives rise to the epidermis; the ground meristem, which produces ground tissue; and the procambium, which produces new xylem and phloem. The epidermis itself is a single layer of cells that cover and protect the underlying tissue in plants, and its formation is crucial for the primary growth, which is growth in length or height of the plant.
