Detailed explanation-1: -Primary dermal tissues, called epidermis, make up the outer layer of all plant organs (e.g., stems, roots, leaves, flowers). They help deter excess water loss and invasion by insects and microorganisms.

Detailed explanation-2: -Dermal tissue covers and protects the plant, and controls gas exchange and water absorption (in roots). Dermal tissue of the stems and leaves is covered by a waxy cuticle that prevents evaporative water loss. Stomata are specialized pores that allow gas exchange through holes in the cuticle.

Detailed explanation-3: -Dermal Tissue Epidermal cells secrete a waxy substance called cuticle, which coats, waterproofs, and protects the above-ground parts of plants. Cuticle helps prevent water loss, abrasions, infections, and damage from toxins. This tissue includes several types of specialized cells.

Detailed explanation-4: -The dermal tissue system-the epidermis-is the outer protective layer of the primary plant body (the roots, stems, leaves, flowers, fruits, and seeds).

Detailed explanation-5: -The primary function of dermal tissue is to protect the plant, control the exchange of water vapor and gasses, and aid in absorption. While the majority of the epidermis is made up of ordinary pavement cells, specialized components throughout enable these functions.
