Vedclass · Answer

(A) The water vascular system (also known as the ambulacral system) is a unique organ system found in echinoderms that functions in locomotion,food capture,respiration,and excretion.This system consists of a network of water-filled canals that connect to external tube feet.The movement of echinoderms is facilitated by the hydraulic pressure of the fluid within the system and the coordinated contraction of the muscles associated with the tube feet.Therefore,the assertion is correct,and the reason provides a correct explanation for how the ambulacral system enables locomotion.

Assertion : Ambulacral system plays a major role in locomotion of echinoderm.
Reason : Hydraulic pressure of fluid and contraction of muscle of tube feet make possible movement of echinoderm.
