What kind of animal is shaped like an umbrella and has string cells?
The animal is a jellyfish. Jellyfish have umbrella-shaped bodies and possess specialized stinging cells called cnidocytes, which they use for prey capture and defense.
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.
Why does a jellyfish has tentacles tha sting?
Jellyfish have tentacles that sting primarily for defense and to capture prey. The tentacles contain specialized cells called cnidocytes, which house stinging structures called nematocysts. When triggered, these nematocysts release toxins that can incapacitate small fish and other prey, making it easier for the jellyfish to feed. Additionally, the stinging mechanism helps protect the jellyfish from potential predators.
Why are cnidocytes important?
Cnidocytes are important because they contain stinging cells that cnidarians, like jellyfish and corals, use for defense and capturing prey. The specialized structure of cnidocytes allows them to quickly discharge venomous barbs when triggered by touch or chemical stimuli. This defense mechanism is crucial for cnidarians' survival in the marine environment.
What is the name of the animal which is shaped like an umbrella and has sting cells?
The animal you are referring to is a jellyfish. Jellyfish have a bell-shaped body that resembles an umbrella and possess specialized cells called cnidocytes that contain stinging structures used for defense and capturing prey.
How does nematocysts work for cnidarians?
All Cnidarians have nematocysts as a specialized organelle. Cnidarians use their nematocysts to capture prey and as a defense mechanism against predators.

What is the function of a nematocyts?
Nematocysts are specialized stinging cells found in cnidarians, such as jellyfish, sea anemones, and corals. Their primary function is to capture prey and provide defense against predators. When triggered, nematocysts release a coiled thread that can inject toxins into the target, immobilizing or harming it. This mechanism is essential for the survival and feeding of these marine organisms.
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 does a jellyfish use its tentacles for?
Jellyfish tentacles have a variety of jobs. Their main purpose is to capture food. Usually they trail behind the jelly to fish for prey. Once contacted, tentacles have specialized cells that sting, stick to, or entangle the prey to immobilize it. The tentacle then contracts and draws the prey towards the mouth of the jellyfish, where oral arms push the food into the oral cavity for consumption. Tentacles sometimes are also used to aid locomotion, grasp onto substrates, and ward off enemies.
Are katydids venomous?
No, katydids are not venomous. They are herbivorous insects that primarily feed on leaves, flowers, and other plant material. They do not possess venom or use it for defense or hunting.
What two functions do nematocysts perform?
Nematocysts are the stinging cells on tentacles of a cnidarian, like a jellyfish. Since jellyfish don't have any teeth, and their body consists of gelatin, it's hard to capture prey. Nematocysts help jellyfish with feeding by stinging the prey in an attempt at trying to immobilizing the prey.
