NEET 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: -Dermal tissue refers to the plant epidermis, the outer layer of tissue that surrounds the primary body of vascular plants. This includes the roots, stems, leaves, flowers, fruits, and seeds. The dermal layer does not contain chloroplasts and is typically composed of a single layer of tightly-packed cells.

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: -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.
