Structural Organisation in Animals

Match List I with List II, related to the digestive system of the cockroach.

List IList II
A. The structure used for storing foodI. Gizzard
B. Ring of 6–8 blind tubules at the junction of foregut and midgutII. Gastric caeca
C. Ring of 100–150 yellow-coloured thin filaments at the junction of midgut and hindgutIII. Malpighian tubules
D. The structure used for grinding foodIV. Crop

Choose the correct answer from the options given below:

  1. A.A-I, B-II, C-III, D-IV
  2. B.A-IV, B-III, C-II, D-I
  3. C.A-III, B-II, C-IV, D-I
  4. D.A-IV, B-II, C-III, D-I✓

Solution

The crop stores food (IV); the gastric caeca are the 6–8 blind tubules at the foregut–midgut junction (II); the Malpighian tubules are the 100–150 yellow filaments at the midgut–hindgut junction (III); the gizzard grinds food (I).
