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 term describes a stinging structure that contains a poisonous harpoon?
Nematocyst.
What is mechanism of nematocyst discharge?
Nematocysts are specialized organelles found in cnidocytes of cnidarians. When triggered by physical contact or chemical stimuli, nematocysts discharge by releasing a tightly coiled tubule that penetrates the prey or predator, injecting venom. The discharge is rapid and usually irreversible, playing a crucial role in the cnidarian's defense and hunting mechanisms.
What is the correct sequence in which a stinging cell reacts to the touch of another organism?
When a stinging cell, also known as a cnidocyte, comes into contact with another organism, it triggers the discharge of a harpoon-like structure called a nematocyst. The nematocyst injects venom into the target, immobilizing or deterring it. This process is crucial for capturing prey or defending against predators in cnidarians such as jellyfish and sea anemones.
Is the transition state the slowest step in a reaction mechanism?
The transition state is not a step in a reaction mechanism; it is a high-energy state that exists at the peak of the reaction potential energy diagram. The slowest step in a reaction mechanism is often referred to as the rate-determining step, which has the highest activation energy and determines the overall rate of the reaction.
What is a stinging mechanism in a cnidocyte?
nematocyst

How does a nematocyst work?
A nematocyst is a stinging cell found in the tentacles of cnidarians like jellyfish and sea anemones. When triggered, the nematocyst fires a coil-like structure that injects venom into its prey or predator, immobilizing or killing it. This mechanism is crucial for the cnidarians' ability to capture and consume food.
Where did the assassination that triggerd World War 1 occur?
It was in Sarajevo.
What causes nematocyst to discharge?
Nematocyst discharge is triggered by an immediate approach or a foreign stimulus. When the cell is discharged, a brand new nematocyst is created as the system in each cell can only be activated once.

What is the poison called that is injected by nematocyst?
venom
What are small barbed harpoon inside a cnidocyte?

How can coral protect itself from enemies?
By corallite and nematocyst .
What does cnidarians use to get food to their mouth?
their tentacles
