Question

The four sketches $(A,B,C$ and $D)$ given below, represent four different types of animal tissues. Which one of these is correctly identified in the options given, along with its correct location and function?

• A. (B) Glandular epithelium - Intestine - Secretion
• B. (C) Collagen fibres - Cartilage - Attach skeletal muscles to bones
• C. (D) Smooth muscle tissue - Heart - Heart contraction
• D. (A) Columnar epithelium - Nephron - Secretion and absorption

Answer 1

The correct option is A (B) Glandular epithelium - Intestine - Secretion

1. The sketch A represents the simple columnar epithelium. It lines the alimentary canal and is involved in absorption and secretion.
2. The sketch B represents the unicellular glandular epithelium and lines the glands including intestine involved in secretion of hormones by the Goblet cells.
3. The sketch C represents the dense regular connective tissue as seen in tendons and ligaments.
4. The sketch D represents the cardiac muscle tissue found in the heart which is striated and involuntary.

So, the correct option is '(B) Glandular epithelium - Intestine - Secretion'.
