Answer» Correct Answer - A Coelenterates possess a very primitive type of nervous system. This system is composed of many nerve cells. In coelenterates, the separate mechanisms for digestion, respiration and excretion, repoduction ect evolved for the first time. Thus there is a constant need to maintain corrdination between these systems. Nerve cells are develope for this purpose, for the first time in coelenterates. Nerve in Hydra is the beginning in the evolution for nervous system. |
