Question

Epidermis and epiblema are produced from
A. Phellogen
B. Calyptrogen
C. Procambium
D. Protoderm.

Answer 1

Hint:A meristematic tissue is a plant tissue that is made up of undifferentiated, actively dividing cells. Its fundamental function is growth. The meristem that gives rise to epidermis, in particular, is referred to as the protoderm. It is located around the outside of the stem.

Complete answer:
To answer this question, first, we need to epidermis and epiblema of plant tissue. Epidermis is the outermost, protoderm-derived layer of cells covering the stem, root, leaf, flower, fruit, and seed parts of a plant. Variety of modified epidermal cells regulates transpiration, increase water absorption, and produce substances. Epiblem is a tissue that removes the epidermis in most roots and in stems of submerged aquatic plants. It is usually present between the epidermis and cortex in the root or stem of a plant.
Now, let us find the solution from the option.
The epidermis is derived from protoderm which forms the external layer of cells which forms covering on the stem, root and leaf of a plant. It is composed of a tough cuticle layer that acts as a shielding bar against mechanical injury, preventing water loss etc.
Epiblema is an outermost single layer of the root. They are the imperfect epidermis that replaces a true epidermis in submerged plants to protect the growing roots from the extremities of the environment.

Thus, the correct option is D.i.e.Protoderm.

Note:In plant body the utmost protoderm transforms into the epidermis which is a tissue that protects the plant The adjacent ground meristem divided into the central ground tissues (the pith and cortex); and the procambium differentiates into the vascular tissues (the xylem, phloem, and vascular cambium).
