Question

In coelenterates, cnidoblasts occur inside

• A. Gastrodermis
• B. Mesogloea
• C. Epidermis
• D. All the above

Answer 1

The correct option is A Gastrodermis

Coelenterates possess a simple gastric cavity, where they digest their food. The gastric cavity communicates with the external environment through a single opening and is lined by an endodermal epithelial layer, or gastrodermis, composed mainly of epitheliomuscular cells, and also gland cells that secrete digestive enzymes and mucus-secreting cells.

So the correct answer is 'Gastrodermis'.
