Protoderm: lies around the outside of the stem and develops into the epidermis. Procambium : lies just inside of the protoderm and develops into primary xylem and primary phloem . It also produces the vascular cambium , and cork cambium (secondary meristems).

The four domains are still present, but they are more defined with the presence of more cells. The important aspect of this stage is the introduction of the protoderm, which is meristematic tissue that will give rise to the epidermis. [12] The protoderm is the outermost layer of cells in the embryo proper. [12]

Cork cambium of woody stem ().It is different from the main vascular cambium, which is the ring between the wood on the inside (top) and the red bast outside it.. Cork cambium (pl.: cambia or cambiums) is a tissue found in many vascular plants as a part of the epidermis.
The cells of the epidermis are structurally and functionally variable. Most plants have an epidermis that is a single cell layer thick. Some plants like Ficus elastica and Peperomia, which have a periclinal cellular division within the protoderm of the leaves, have an epidermis with multiple cell layers. Epidermal cells are tightly linked to ...
Plants that have been used for bast fibre include flax (from which linen is made), hemp, jute, kenaf, kudzu, linden, milkweed, nettle, okra, paper mulberry, ramie ...
Parenchyma is a versatile ground tissue that generally constitutes the "filler" tissue in soft parts of plants. It forms, among other things, the cortex (outer region) and pith (central region) of stems, the cortex of roots, the mesophyll of leaves, the pulp of fruits, and the endosperm of seeds.
