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.

What is a nematocyst and how does it work?
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.
What are the types of mechanical work?
The types of mechanical work include static work, dynamic work, and intensive work. Static work refers to work done without motion, dynamic work involves movement, and intensive work focuses on the internal energy changes within a system.
How does input work and out put work affect the efficiency of a simple machine?
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
What formula relates work and power?
The formula that relates work and power is: Power = Work / Time. Power is the rate at which work is done, which is the amount of work done divided by the time it takes to do that work.
The work that the simple machine does is called the work?
the work a machine does is the work output what it takes to do the work is the work input

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.
