Where are two main locations of nematocysts?
Nematocysts are found in sea creatures, specifically jellyfish and anemones. The nematocyst is an organelle found in these creatures that enables them to fire toxins. These toxin-causing nematocysts are responsible for the stinging capabilities of jellyfish, anemones, and other cnidocytes.

What are the types of nematocysts?
Nematocysts are specialized stinging cells found in cnidarians, such as jellyfish, corals, and sea anemones. There are several types of nematocysts, including penetrant nematocysts, which inject toxins into prey or predators; glutinant nematocysts, which adhere to surfaces or prey; and volvent nematocysts, which wrap around and immobilize prey. Each type serves a specific function in capturing prey or defense against threats.
Explain how cnidocytes with their nematocysts function in food capture and defense?
Cnidocytes are specialized cells found in cnidarians that contain stinging structures called nematocysts. When triggered, nematocysts shoot out barbed threads that inject toxins into prey for food capture. In defense, nematocysts can be used to deter predators by stinging them.
What is nematocysts?
Nematocysts are specialized stinging cells found in the tentacles of cnidarians, such as jellyfish and sea anemones. They are used for defense and prey capture by injecting toxins into their target. When triggered, nematocysts release a coiled thread that can penetrate the skin of the prey or predator.
What structure are the stinging cells of cnidarians located?
The stinging cells of cnidarians, called cnidocytes, are located on specialized structures called nematocysts. These nematocysts are found on the tentacles of cnidarians and are used for defense and capturing prey.
What are cnidae an nematocysts?
Cnidae are specialized organelles found in cnidarians, such as jellyfish, corals, and sea anemones. Nematocysts are a type of cnidae that function as stinging cells, containing a coiled, harpoon-like filament that can be explosively discharged to capture prey or deter predators. When triggered, nematocysts inject toxins into their target, playing a crucial role in the cnidarian's feeding and defense mechanisms.
Which two functions do nematocysts perform?
Nematocysts are specialized organelles found in the stinging cells of cnidarians. Their main functions are to inject toxins into prey or threats for defense and to aid in capturing and immobilizing prey using barbs or sticky threads.
How often can the mechanism in nematocysts be triggered?
Only once. After discharge, nematocysts are absorbed by the cnidarian and new nematoblasts must be created from interstitial stem cells (often at the base of the tentacle) and while differentiating into new nematocysts they also travel down the tentacle between epithelial layers to their final destination (in species specific patterns) within the ectoderm. This is not only an amazing process, but provides an explanation for the often complex triggering mechanisms that befits this 'expensive' resource of cnidarians.
Where are nematocysts located?
Nematocysts are located on the tentacles of cnidarians, such as jellyfish and anemones. They are specialized stinging cells used for capturing prey and defending against predators. When triggered, nematocysts release a harpoon-like structure that injects toxins into the target.
What phylum has nematocysts?
Phylum Cnidaria
What is a capsule on a cnidarians tentacle called?
Nematocysts
