AP BIOLOGY

Detailed explanation-1: -The dermal tissue system-the epidermis-is the outer protective layer of the primary plant body (the roots, stems, leaves, flowers, fruits, and seeds). The epidermis is usually one cell layer thick, and its cells lack chloroplasts.

Detailed explanation-2: -The dermis is a connective tissue layer sandwiched between the epidermis and subcutaneous tissue. The dermis is a fibrous structure composed of collagen, elastic tissue, and other extracellular components that includes vasculature, nerve endings, hair follicles, and glands.

Detailed explanation-3: -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.

Detailed explanation-4: -The dermal tissue usually consists of a single layer of tissues showing variations in the types of cells on the basis of their function and location. These tissues are divided into three different types. They are epidermis (outer most layer), (middle layer) and endodermis (innermost layer).

Detailed explanation-5: -Dermal tissue covers the outside of a plant in a single layer of cells called the epidermis. You ca n think of the epidermis as the plant’s skin. It mediates most of the interactions between a plant and its environment.
