Front

What is the function of the water vascular system in echinoderms?

Back

The water vascular system is a network of canals that helps in locomotion, feeding, and gas exchange in echinoderms.

Front

What type of skeleton do echinoderms possess?

Back

Echinoderms have an endoskeleton made of calcareous plates.

Front

What is the role of tube feet in sea stars?

Back

Tube feet are used for movement, feeding, and sensing the environment.

Front

What is the function of the ampulla in echinoderms?

Front

What is the madreporite in echinoderms?

Back

The madreporite is a sieve-like structure that regulates water flow into the water vascular system.
