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.

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 two functions do nematocysts perform?
Nematocysts in cnidarians serve two main functions: capturing prey by injecting venom and providing defense against predators. The nematocysts contain a coiled thread that shoots out upon contact, delivering the venom to immobilize or deter the threat.
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.
What is one type of cell all cnidarians have?
All cnidarians have specialized stinging cells called cnidocytes, which contain harpoon-like structures called nematocysts used for defense and capturing prey.
What part of the hydra contains the stinging cells?
The stinging cells in a hydra are located in the tentacles, which are cylindrical, tube-like structures surrounding the mouth of the organism. These stinging cells, called cnidocytes, contain nematocysts that can inject toxins into prey or threats.
Where are the nematocysts of the hydra located?
The nematocysts are stinging cells of cnidarians located all along the feeding tentacles. These cells are inverted "harpoons" that react physically and chemically to stimuli at a speed of 1/1000th of a sec.
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 type of animal uses toxins on nematocysts to capture prey?
Jellyfish use toxins in nematocysts to capture and immobilize their prey. The nematocysts are specialized cells located on their tentacles that inject venom into the prey upon contact.
What are the stinging cells located on the tentacles of a jellyfish?
Jellyfish sting their prey using nematocysts, also called cnidocysts, stinging structures located in specialized cells called cnidocytes.
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.
Nematocysts are found only in what?
Nematocysts are are only found in the animal phylum Cnidaria, which includes sea anemones, corals, and jellyfish.
What do cnidarians use to defend themselves?
cnidarians have stinging cells called nematocysts located on their tantacles
What phylum has nematocysts?
Phylum Cnidaria
Stinging structures of jellyfish are?
Jellyfish sting their prey using nematocysts, also called cnidocysts, stinging structures located in specialized cells called cnidocytes.
What are stinging cells called?
Jellyfish sting their prey using nematocysts, also called cnidocysts, stinging structures located in specialized cells called cnidocytes.
What causes jellyfish stings?
Jellyfish venom is delivered by barbs called nematocysts, which are located on the creature's tentacles and penetrate the skin of people who brush up against them.
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.
