Tissue is a group of similarly structured cells that perform a similar function in an organism. Animal tissues are divided into four main categories: epithelial tissues, connective tissues, muscle tissues, and nervous tissues. In plants, tissues consist of three categories: dermal tissues, vascular tissues, and ground tissues.
