Function of Malpighian tubules of cockroach :
(a) Respiration
(b) Digestion
(c) Excretion
(d) Reproduction

Options

A. Respiration
B. Digestion
C. Excretion
D. Reproduction

Answer

**Step-by-Step Solution:**

1. **Understanding Malpighian Tubules**: Malpighian tubules are specialized structures found in cockroaches that serve a specific function within the insect's body.

2. **Location**: These tubules are located at the junction of the midgut and hindgut of the cockroach. This positioning is crucial for their function in waste management.

3. **Function**: The primary function of Malpighian tubules is excretion. They act as excretory organs, helping to remove metabolic waste from the cockroach's body.

4. **Mechanism of Action**: Malpighian tubules extract waste products from the hemolymph (the insect equivalent of blood) and facilitate the removal of these wastes. They also play a role in the absorption of excess water and solutes.

5. **Conclusion**: Based on the above information, the function of Malpighian tubules in cockroaches is primarily related to excretion. Therefore, the correct answer to the question is option (c) Excretion.

**Final Answer**: (c) Excretion
