Phylum Cnidaria - SlideShare Cnidocyte Structure and Nematocyst Discharge. (a) A nematocyst develop in the capsule in the cnidocyte. The capsule is capped at its outer margin by an operculum that is discharge of the nematocyst. The trigger like cnidocil is resposible for nematocyst discharge. (b) A discharge nematocyst.

Nematocysts - The Stinging Cells | Zoology for IAS, IFoS and other ... MECHANISM OF DISCHARGE The discharge of nematocyst thread tube from the cnidocyte takes place due to mechanical or chemical stimuli received by the cnidocil. In a resting stage the capsule wall is not permeable to water and there is very high osmotic pressure since the hypnotoxin inside is hypertonic to external water. Cnidocyte - Wikipedia A cnidocyte (also known as a cnidoblast or nematocyte) is an explosive cell containing one large secretory organelle called a cnidocyst (also known as a cnida (pl. cnidae) or nematocyst) that can deliver a sting to other organisms.The presence of this cell defines the phylum Cnidaria (corals, sea anemones, hydrae, jellyfish, etc.).Cnidae are used to capture prey and as a defense against predators.

The cnidarian nematocyst: a miniature extracellular matrix within a ... Nematocyst discharge, which is one of the fastest processes in biology, is driven by an extreme osmotic pressure of about 150 bar. The molecular analysis of the nematocyst has from the beginning indicated a collagenous nature of the capsule structure.

nematocyst | biology | Britannica nematocyst, minute, elongated, or spherical capsule produced exclusively by members of the phylum Cnidaria (e.g., jellyfish, corals, sea anemones). Several such capsules occur on the body surface. Each is produced by a special cell called a cnidoblast and contains a coiled, hollow, usually barbed thread, which quickly turns outward (i.e., is everted) from the capsule upon proper stimulation ...
