Answers
Coelenterates are organisms belong to the Phylum Coelenterata also knon as Cnidaria. This phylum is composed of about 9,000 species. The name Coelenterata implies to a group of animals that posses a single large central cavity coelenteron - intestine or gastrovascular cavity with a single opening that serves both as anus and mouth. These organisms are multicellular.
The special cells that serve as organs of defence and offence in coelenterates are called cnidoblasts. These cells are found in fingure-like structures tentacles and they are embedded in Cnidocytes and nematocytes which are the organs of offence and defence.
The cell serving both for the purpose of offense and defense is cnidocyte.
It plays a very important role as it helps in both capturing the prey as well as defending the organism from the predator.
