There are two kinds of tissues in plants, i.e., permanent tissues and meristematic tissues. find epithelial cells. lines every body surface and all body cavity; thus it forms both the external and internal lining of many organs, and it constitues the majority of glands. The glandular epithelium lines various glands and their ducts throughout the body, which then later proliferate to produce various hormones and enzymes. These two tissue types have the common function of protection from foreign bodies and toxins, as well as mechanical damage. What is the difference between muscles and nerves?
