A tissue is a group of cells that work together to perform a specific function. Animal tissues include connective, muscle, nervous and epithelial. Epitheiial tissue protects, secretes and absorbs. It can be found in the lining of the digestive system, airways and the surface of skin. Connective tissue gives shape to organs and keeps them in position. It supports other tissues in the body. Muscle tissue allows for motion and can be categorized as smooth, skeletal and cardiac muscle. Nervous tissue forms the brain and spinal cord as well as nerves. Plant tissues include vascular tissue. This is conducting tissue and is comprised of xylem which transports water and phloem, which transports food. There is epidermal tissue and ground tissue in plants--epidermal tissue is located on the outer surface of leaves. Ground tissue manufactures and stores nutrients. Plants have meristematic tissue which actively divides and adds to the height of plants and adds to the thickness of the plant also. These are just a few tissue types found in animals and plants.
The plant tissue(s) is the tissue of the plant- composed of many cells functioning together.e.g dermal tissue- consisting of various cells 'working together' to provide support and protection for the plant.
