Biomineralization is that the method by those living organisms turns out minerals, usually to harden or stiffen existing tissues. Such tissues are referred to as mineralized tissues. The condition of inorganic materials with complicated form may be a widespread biological development (biomineralization) that happens in most teams of organisms from prokaryotes (e.g., iron ore nanocrystals in bound bacteria) to humans (bone and teeth). Among the foremost spectacular samples of biomineralization are the elaborately structured cell walls of diatoms, an outsized cluster of a cellular being protoctist that is gift in most water habitats.
