NEET 2025 · BiologyEchinodermataPrevious Year Question
Role of the water vascular system in Echinoderms is: A. Respiration and Locomotion B. Excretion and Locomotion C. Capture and transport of food D. Digestion and Respiration E. Digestion and Excretion Choose the correct answer from the options given below:
Answer: (D) A and C Only. In echinoderms the water vascular system helps in locomotion, capture and transport of food, and respiration.
- A.B and C Only
- B.B, D and E Only
- C.A and B Only
- D.A and C Only✓
Correct Answer
(D) A and C Only
Solution & Explanation
In echinoderms the water vascular system helps in locomotion, capture and transport of food, and respiration. So statement A (Respiration and Locomotion) and statement C (Capture and transport of food) are correct, giving option (d). Excretion and digestion are not functions of the water vascular system (an excretory system is in fact absent in echinoderms). NCERT Reference: Page 45, line 18-20
