Compare plasma emission with fluorescence by indicating what is common and what is different for the two light emitting mechanisms.

Plasma is a state of matter, generated when a gas of ions and atoms, have some of their orbital electrons and free electrons removed. Artificially, plasma can be generated by heating an electrically neutral gas, or subjecting the gas to a strong electromagnetic field until the gas becomes increasingly electrically conductive. This excited atoms and ions then emit electromagnetic radiation usually within the visible range, at wavelengths characteristic of the particular gas used, and are confined by a strong magnetic field.

On the other hand, fluorescence occurs when an excited molecule, atom, or subatomic particles like electrons relaxes to a lower energy state (possibly the ground state) by emitting energy in the form of a photon. It may have been directly excited from the ground state by absorbing energy in the form of a photon, subsequently emitting a photon of lower energy as it relaxes back to its initial lower state.

The common characteristics between these two phenomenon is that they both lead to the emission of energy in the form of photons, which is the unit of an electromagnetic energy or wave.

The difference is that plasma emission can only occur at a very high temperature, whereas fluorescence can occur at a wide range of temperatures between high and low temperatures.

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.
