The mechanism in the nematocyst can be triggered in response to various stimuli, such as physical contact, chemical signals, or changes in water pressure. This triggering can occur rapidly, often within milliseconds, allowing the nematocyst to effectively capture prey or defend against predators. However, the frequency of triggering can vary based on species, environmental conditions, and the specific context of interaction. In general, nematocysts can be triggered multiple times throughout an organism's life, but individual cells are typically only used once before being regenerated.
The trigger mechanism of the nematocyst organelle of the stinging cnidocyte cell consists of a sensory hair and a chemical receptor. When the sensory hair is mechanically stimulated, it activates the chemical receptor, leading to the discharge of the nematocyst's venomous contents.
Nematocysts are specialized organelles found in cnidocytes of cnidarians. When triggered by physical contact or chemical stimuli, nematocysts discharge by releasing a tightly coiled tubule that penetrates the prey or predator, injecting venom. The discharge is rapid and usually irreversible, playing a crucial role in the cnidarian's defense and hunting mechanisms.
A stinging cell, such as the nematocyst in cnidarians, is a specialized capsule containing a coiled thread. When triggered, the thread is expelled rapidly to inject venom into prey or predators. This venom can paralyze or immobilize the target.

A nematocyst is a stinging cell found in the tentacles of cnidarians like jellyfish and sea anemones. When triggered, the nematocyst fires a coil-like structure that injects venom into its prey or predator, immobilizing or killing it. This mechanism is crucial for the cnidarians' ability to capture and consume food.

Nematocyst discharge is triggered by an immediate approach or a foreign stimulus. When the cell is discharged, a brand new nematocyst is created as the system in each cell can only be activated once.

Nematocytes, more commonly referred to as nematocysts, are specialized stinging cells found in cnidarians, such as jellyfish, sea anemones, and corals. These cells contain a unique structure called a nematocyst, which is capable of injecting toxins into prey or potential threats. When triggered, nematocysts rapidly discharge a coiled thread that can penetrate skin and deliver venom. This mechanism is crucial for the defense and feeding of cnidarians.
All Cnidarians have nematocysts as a specialized organelle. Cnidarians use their nematocysts to capture prey and as a defense mechanism against predators.
