Question: 159: Match List-I with List-II regarding the organs of Cockroach:
| List-I | List-II |
|---|---|
| (a) Crop | (i) grinding the food particles |
| (b) Proventriculus | (ii) secretion of digestive juice |
| (c) Hepatic caecae | (iii) removal of nitrogenous waste |
| (d) Malpighian tubules | (iv) storage of food |
Choose the correct answer from the options given below:
(1) (a) – (iv), (b) – (i), (c) – (ii), (d) – (iii)
(2) (a) – (iii), (b) – (ii), (c) – (i), (d) – (iv)
(3) (a) – (ii), (b) – (iv), (c) – (i), (d) – (iii)
(4) (a) – (i), (b) – (iv), (c) – (iii), (d) – (ii)
Answer: Option (1)
Explanation:
The crop of cockroach is a thin-walled structure that temporarily stores food before digestion.
The proventriculus, also called the gizzard, has chitinous teeth and helps in grinding the food particles.
Hepatic caecae are finger-like projections that secrete digestive enzymes and aid in digestion.
Malpighian tubules are excretory organs responsible for removal of nitrogenous waste from the body.
Thus, the correct matching is (a) – (iv), (b) – (i), (c) – (ii), and (d) – (iii).
