WebAug 13, 2024 · August 13, 2024 by World Wide FAQS. In summary we suggest that three driving forces are involved in the discharge of nematocysts, all resulting from a loss of protons: electrostatic repulsion, generation of osmotic pressure, and conformational change at the inner tubule’s surface. How does a nematocyst work How quickly does it discharge? WebNov 25, 2024 · A cnidocyte is an explosive cell having within it a giant secretory organelle (organ) called cnida which is a characteristic of the phylum Cnidaria. A Nematocyst is a specialized sub-cellular organelle (part of the cell) present in cnidocyte. Thus, a nematocyst is essentially a part of a cnidocyte.

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.
