Tissue is composed of cells that are similar in structure and function, and that work together to perform specific tasks within an organism.
Tissue is composed of cells. Cells are the basic structural and functional units of all living organisms, and when they come together and perform specific functions, they form tissues. Tissues can be classified into four main types: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Each type of tissue is made up of specialized cells that work together to carry out specific functions in the body.
