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.

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 ... cnidarian_webquest (1).pdf - Name:Molly Harnaga Date:...

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. In particular, a large family of unusual minicollagens has been demonstrated to form the ...

Phylum Cnidaria - SlideShare Nematocysts are a type of cnida used in food gathering and defense that may discharge a long tube armed with spines that penetrates the prey. The spines has hollow tips that deliver paralyzing toxins. Other cnidae contain unarmed tubes that wrap around prey or a substrate.
