A student was given a sample of tissue. He observes and concludes the following characters. (i) The following The cells are composed of a single layer of tall and slender cells. (ii) Their nuclei are located at the base. (iii) Free surface may have microvilli . (iv) It is found in the lining of stomach and intestines (v) It help in secretion and absorption. Based on the above features identify the epithelium.
