Question

What are Nematocysts in Coelenterates?

Answer 1

Nematocysts in Coelenterates:

1. The nematocysts of cnidoblasts, also known as cnidocytes, are the phylum Coelenterata's distinguishing trait.
2. Coelenterates are multicellular aquatic animals that live in colonies and are typically marine. They feature radial symmetry and tissue-level structure.
3. Members of this phylum lack the respiratory, circulatory, and excretory systems. The general body surface is used for respiration and excretion.
4. On the basis of the evolution of zooids, coelenterates are further divided into three classes: Anthozoa, Anthozoa, and Anthozoa, Anthozoa, and Anthozoa, Anthozoa, and Anthozoa, Anthozoa, and An Scyphozoa and Hydrozoa are two types of bacteria.
5. Jellyfish, coral creatures, and sea anemones are examples of coelenterates.
