They are not composed of cells. That alone is enough to put them in the category of non-living. Plus they do not carry out metabolism, and they do not reproduce. They also have no genetic material.

∙ 14y agoThere are many reasons, but one is that they do not contain cells. Cells are regarded in the cell theory to be the basic building block of life. If something does not contain at least one cell, it is not alive. Thus, bacteria are alive, but viruses can be considered nonliving. Annother reason is because crystal salts have a distinct chemical composition (ex NaCl sodium chloride or KCl potassium chloride). Therefore, they are compounds and compounds cannot be living.

Egg-living or non living thing?
All animals are living things, there is no problem there. The problem with the definitions of 'life' and 'living thing' first arises with the viruses as they: # do not manipulate energy to perpetuate their own existence # do not have everything within themselves to perform their functional existence but rely on the functional organs of a host to complete them. Problems with the definition gets even harder with the prions as they do not even have DNA or RNA to define them but are merely perpetuating proteins maintained within another living organism. (mad cow deases, Scrapies, etc.) Crystals meet some of the definitions of a living thing as they untilize energy in the form of heat and chemiical concentrations to grow and reproduce (under the right conditions), and carry within themselves all the information necessary to perpetuate their particular existence, but nobody seriously considers them to be a living thing.
