A researcher working on glandular epithelial tissue observed that when sebaceous glands of mammals produced its secretion, the atypical part of the secretary cell comes out along with the secretion.
(i) To which group of glandular epithelium would you classify it?
(ii) This secretion is like baby's first vaccine containing antibodies. What are these antibodies made of?
(A) (i) - Apocrine gland; (ii) - Proteins
(B) (i) - Merocrine gland; (ii) - Lipids
(C) (i) - Apocrine gland; (ii) - Lipids
(D) (i) - Merocrine gland; (ii) - Proteins

Explanation:
The glandular epithelium is a type of epithelial tissue which covers the glands (both exocrine and endocrine) of our body. They are mainly of two types: unicellular, consisting of isolated glandular cells (goblet cells of the alimentary canal), and multicellular, consisting of a cluster of cells (salivary gland).
The major function of glandular epithelium is secretion. For example, Goblet cells of intestine secrete mucus.
Glandular epithelium forms the covering of all major glands. It is also present in the intestinal lining.
Hence Tissue - Glandular epithelium Location - Intestine Function - Secretion is correctly matched with its location and function.
So, the correct answer is 'Tissue - Glandular epithelium Location - Intestine Function - Secretion'.
