AP BIOLOGY

Detailed explanation-1: -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-2: -The cuticle is located outside the epidermis and protects against water loss; trichomes discourage predation. The mesophyll is found between the upper and lower epidermis; it aids in gas exchange and photosynthesis via chloroplasts.

Detailed explanation-3: -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-4: -Dermal tissue is a thin layer of cells covering the soft parts of a plant. The dermal tissue system protects the soft tissues of plants and controls interactions with the plants’ surroundings. The epidermis is a dermal tissue that is usually a single layer of cells covering the younger parts of a plant.

Detailed explanation-5: -The cuticle is a thin layer that is found on the outer layer of the epidermal tissue. This layer is found only on stems and prevents water loss.
