Question

Digestion in coelenterates is

• A. only intracellular
• B. only extracellular
• C. both extracellular and intracellular
• D. not required

Answer 1

The correct option is C both extracellular and intracellular

Digestion is both extracellular as well as intracellular in coelenterates. First, there is extracellular digestion in gastrovascular cavity where digestive enzymes from cells bordering the cavity are poured onto the food. The smaller particles of the partially digested food are then engulfed into vacuoles of the digestive cells for intracellular digestion.
