Answer:
The tissue being described is the epidermal tissue. It is a type of plant tissue that covers the outer surface of the plant body and protects it from external damage, including injury, water loss, and infection. The epidermal tissue is found on all plant organs, including roots, stems, leaves, flowers, fruits, and seeds. It consists of a single layer of cells and may contain various types of specialized cells, such as guard cells, trichomes, and root hairs, depending on the organ and its function. The epidermal tissue also plays a role in gas exchange, water absorption, and secretion.
