The correct matching of the cells and their functions is D) melanocytes -- protect cells from the effects of UV radiation. What are the cells and their functions? Cells are the basic unit of life. They are the building blocks of living organisms. Cells are specialized to perform specific functions that are necessary for the survival of the organism. The body is made up of trillions of cells that work together to carry out different functions. Cells in the human body have different shapes, sizes, and functions. They are classified into four types: epithelial, connective, muscular, and nervous. Each type of cell has a specific function that is essential for the proper functioning of the body. The following are the correct matching of cells and their functions: Keratinocytes: These are the cells that make up the majority of the epidermis, which is the outermost layer of the skin. The function of keratinocytes is to produce keratin, a protein that provides protection to the skin from the environment. Tactile cells: These are also called Merkel cells. The function of tactile cells is to provide the sense of touch and pressure. Dendritic cells: These cells are part of the immune system. The function of dendritic cells is to capture foreign particles and present them to the immune system for recognition. Melanocytes: These cells produce a pigment called melanin, which gives color to the skin. The function of melanocytes is to protect the cells from the harmful effects of UV radiation by absorbing the radiation and preventing damage to the DNA.
