Simple tissue is made up of the same type of cells and mostly covers the surface of both, internal organs of the body and external organs of the body. This tissue is called epithelium in animals and epidermis in plants. The intercellular spaces in this tissue are absent because in intercellular spaces at the corner of cells thickenings of cellulose and pectin develop due to which the cell wall become rigid and thick at corners. They cover the surface of the ovary, epididymis, and parts of the testes. They form the external skin, the inner lining of the mouth, digestive tract, secretory glands, the lining of hollow parts of every organ such as the heart, lungs, eyes, ears, the urogenital tract, as well as the ventricular system of the brain and central canals of the spinal cord. Answer: On the basis of constituent cells, permanent tissues can be classified into three categories: simple tissue, complex tissue, special tissues. They are living. 2.
