Describe, in disgusting detail what a nematocyst does and how it does its job.

Nematocyst are the stinging cells found in jelly fishes. These are found in the tentacles which helps in prey capture.

The tentacles are lined with number of capsules inside the cell called nematocyst. Inside the capsule thread like projections are present. It contains toxins which paralyses the captured prey.

When the jelly fish captures the prey, with help of tentacles these thread like projections are pierced into the prey's body and release toxins to kill it.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
