Given below are two statements: Statement I: Goblet cells are unicellular glands. Statement II: Earwax is the secretion of exocrine gland. In the light of the above statements, choose the correct answer from the options given below:
Answer: (A) Both Statement I and Statement II are true. Answer: (A) [option (1)] Both Statement I and Statement II are true.
- A.Both Statement I and Statement II are true✓
- B.Both Statement I and Statement II are false
- C.Statement I is true but Statement II is false
- D.Statement I is false but Statement II is true
Correct Answer
(A) Both Statement I and Statement II are true
Solution & Explanation
Answer: (A) [option (1)] Both Statement I and Statement II are true. Solution: Glandular epithelium arises when columnar/cuboidal cells specialise for secretion. It is of two kinds: UNICELLULAR (isolated glandular cells) and MULTICELLULAR (clusters of cells). GOBLET CELLS of the alimentary canal are the classic example of UNICELLULAR glands — so Statement I is TRUE. On the mode of secretion, glands are exocrine or endocrine. EXOCRINE glands release their products through ducts and include glands secreting mucus, saliva, EARWAX (cerumen), oil, milk and digestive enzymes — so earwax is indeed an exocrine-gland secretion, making Statement II TRUE. Hence both statements are true.
