GENERAL HISTOLOGY

Detailed explanation-1: -Cnidarians contain specialized cells known as cnidocytes (“stinging cells”) containing organelles called nematocysts (stingers). These cells are present around the mouth and tentacles, and serve to immobilize prey with toxins contained within the cells. Nematocysts contain coiled threads that may bear barbs.

Detailed explanation-2: -Cnidarians, including jellyfish and sea anemones, both detect and capture prey using stinging cells called nematocytes which fire a venom-covered barb via an unknown triggering mechanism.

Detailed explanation-3: -Cnidocytes, also known as stinging cells, are specialized neural cells that typify the phylum Cnidaria (sea anemones, corals, hydroids, and jellyfish) [1, 2, 3]. These cells contain an organelle called cnida or cnidocyst, which is the product of extensive Golgi secretions.

Detailed explanation-4: -They are invertebrates belonging to the class of Anthozoa. The name Cnidaria (with a silent ‘c’) refers to the cnidae, or nematocysts, that is, the cellular entity of the venom apparatus, which all Cnidarians possess. The phylum Cnidaria includes anemones, corals, jellyfish (including box jellyfish), and hydras.

Detailed explanation-5: -Animals from the phylum Cnidaria have stinging cells called cnidocytes. Cnidocytes contain large organelles called (a) nematocysts that store a coiled thread and barb, the nematocyst.
