nematocyst
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.
DNA coiled up into thread-like structures is called chromatin. Chromatin consists of DNA wrapped around proteins called histones, which helps to package and organize the genetic material inside the nucleus of a cell.
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.
A coiled piece of DNA is called a plasmid, found in prokaryotic cells.
Stinging cells on cnidarians are known as cnidocytes. These specialized cells contain structures called nematocysts, which can eject a toxic thread to capture prey or deter predators. This unique mechanism is a key feature of cnidarians, which include organisms such as jellyfish, corals, and sea anemones.
Chromotins are thread-like DNA before it is being coiled up.
A nematocyst is a specialized stinging cell found in the tentacles of cnidarians like jellyfish and sea anemones. When triggered by a physical contact or a chemical stimulus, the nematocyst releases a coiled thread that can inject venom into the prey or predator. This helps the cnidarian defend itself or capture prey.
Cnidarians posses special stinging cells called cnidocytes or nematoblasts. Each cnidocyte acts as a capsule and encloses a namatocyst. The namatocyst is filled with a poisonous fluid, hypotoxin, and its anterior end is drawn out into a long hollow thread which may bear spines. On being stimulated, the nematocyst is ejected and its long thread either injects poisons into the body of prey, killing or paralysing it or coils around it. Thus these help in food capture, offence and defence and in adhesion.
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.
Cnidocytes are specialized stinging cells found in the tentacles of cnidarians, such as jellyfish and sea anemones. They contain nematocysts, which are small capsules that deliver toxins to prey or predators when triggered.
The long thread-like structure of DNA is called a "chromosome." Chromosomes are made up of DNA tightly coiled around proteins called histones, which help package the DNA into a compact form that fits within the cell nucleus. In humans, each cell typically contains 23 pairs of chromosomes, carrying the genetic information necessary for development and functioning.
Cnidocytes are specialized cells found in cnidarians that contain stinging organelles called nematocysts. These cells are important for prey capture, defense against predators, and competition for resources. When triggered, cnidocytes release the nematocysts, which inject toxins into the prey or predator, aiding in immobilization or deterrence.
