How do stinging nettle trichomes contribute to the plant's defense mechanism against herbivores?
Stinging nettle trichomes are tiny hairs on the plant that contain irritating chemicals. When touched, these trichomes break and release the chemicals, causing a stinging sensation. This defense mechanism deters herbivores from eating the plant, protecting it from being consumed.

What are 2 adaptations for the stinging nettles?
Stinging nettles have stinging hairs that release irritating chemicals when touched, deterring herbivores and humans from eating them. They also have a robust root system that allows them to quickly colonize disturbed environments and outcompete other plants.
How do stinging cells help a hydra captue food?
Stinging cells in a hydra, known as cnidocytes, contain harpoon-like structures that can inject venom into prey. When prey brushes against these cells, the stinging mechanism is triggered, paralyzing or killing the prey. This allows the hydra to easily capture and consume its food.
Did a wasp land on you without stinging?
Yes, a wasp can land on you without stinging.
Is stinging nettle poisonous and can it cause harm if touched or ingested?
Yes, stinging nettle can cause harm if touched due to its stinging hairs that release irritating chemicals. Ingesting stinging nettle can also cause mild to moderate side effects, but it is generally considered safe when cooked or prepared properly.
How can I prevent a cut from stinging in the shower?
To prevent a cut from stinging in the shower, you can try covering it with a waterproof bandage or applying a thin layer of petroleum jelly before getting in the water. This can help protect the cut from the water and reduce the stinging sensation.
What is a stinging mechanism in a cnidocyte?
nematocyst
What are 2 adaptations for the stinging nettles?
Stinging nettles have stinging hairs that release irritating chemicals when touched, deterring herbivores and humans from eating them. They also have a robust root system that allows them to quickly colonize disturbed environments and outcompete other plants.
Do bees only sting people?
Stinging is the self defense mechanism and can be used against any attacking animal.
The trigger mechanism of the nematocyst organelle of the stinging cnidocyte cell consists of a and a?
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.
What are some plants with physical defense?
Plants with physical defense mechanisms include those with thorns or spines (such as roses or cacti), hairs or trichomes (like stinging nettle or poison ivy), and tough outer shells or rinds (like coconuts or chestnuts). These defenses help protect the plants from herbivores and reduce the likelihood of being eaten.
Do termites have stingers?
No, termites do not have stingers. Instead of stinging, they defend themselves by biting with their mandibles. Some termite species can also release chemicals or pheromones as a form of defense. Overall, their primary means of protection relies on their biting ability rather than a stinging mechanism.
Animals that contain stinging cells?
Animals that contain stinging cells, known as cnidocytes, primarily belong to the phylum Cnidaria. This includes jellyfish, sea anemones, corals, and hydras. These specialized cells contain structures called nematocysts, which can deliver toxins to capture prey or defend against predators. The stinging mechanism is a key adaptation for survival in their aquatic environments.
What is the present progressive tense of sting?
I am stinging. You are stinging. He/she/it is stinging. We are stinging. They are stinging. (Of course, normally only the 3rd person, it or they, would be used with sting.)
What would happen if a cnidarian lost its stinging cells?
If a cnidarian lost its stinging cells, it would lose its primary defense mechanism against predators and its ability to capture prey. This would make the cnidarian more vulnerable to predation and reduce its efficiency in obtaining food.
Stinging cells on cnidarians are known as what?
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.
How do stinging cells help a hydra captue food?
Stinging cells in a hydra, known as cnidocytes, contain harpoon-like structures that can inject venom into prey. When prey brushes against these cells, the stinging mechanism is triggered, paralyzing or killing the prey. This allows the hydra to easily capture and consume its food.
What bee dies after stinging?
Honeybees are the bees that die after stinging. When a honeybee stings, it leaves behind its stinger and part of its abdomen, which ultimately leads to its death. This is a defense mechanism to protect the hive, and the bee sacrifices itself in the process. Other types of bees, like bumblebees, can sting multiple times without dying.
