Compare and contrast the process of digestion in cnidarians and echinoderms.

cnidaria - incomplete digestion [have only a single opening] **, digestion is extracellular and intracellular ,**they have stinging casules called cnidoblast which helps for anchorage,defence and capture prey. echinodermata - complete digestion[mouth on ventral,anus on dorsal],have water vascular system helps in locomotion ,capture of prey,transport of food....digestion is intracellular

Some of the major difference in the digestive system of Cnidarians and echinoderm are

Cnidarians have an incomplete digestive system specifically extracellular digestion occur, where enzymes break down the food particles are degraded by enzymes and absorption occur in its gastrovascular cavity.
While in echinoderms , the digestive system may vary depending on types of species and need of their food types.
They use of tube feet to reach to their food sources and move their mouth area toward the food. Their digestive system relatively simple when compare with human .

Cnidarians possess an incomplete digestive system with a gastrovascular cavity that serves as both mouth and anus, relying on extracellular digestion. Echinoderms have a complete digestive system with separate mouth and anus, using tube feet for feeding and a water vascular system for gas exchange. Both groups use extracellular digestion but differ significantly in their digestive structures and processes.
