Verified step by step guidance

Step 1: Begin by understanding the hierarchical organization of the human body. The body is organized into cells, tissues, organs, and organ systems. Each level has distinct characteristics and functions.

Step 2: Define the term 'organ.' An organ is a structure composed of multiple types of tissues working together to perform specific functions. Examples include the heart, lungs, and skin.

Step 3: Analyze the structure of the skin. The skin consists of multiple layers, including the epidermis, dermis, and hypodermis, each made up of different types of tissues such as epithelial tissue, connective tissue, and nervous tissue.

Step 4: Compare the skin to the other options provided in the question. A membrane is a thin layer of tissue that covers surfaces or separates areas, a cell is the basic unit of life, and a tissue is a group of similar cells working together. The skin, however, is composed of multiple tissue types, making it an organ.

Step 5: Conclude that the skin is best described as an organ because it fulfills the criteria of being composed of multiple tissues working together to perform specific functions, such as protection, sensation, and temperature regulation.
