The recipient vessel is transparent and configured to retain a liquid solution and the plurality of diatoms. The liquid solution may be seawater or freshwater depending on the species of the plurality of diatoms used. Reproduction among these organisms is asexual by binary fission, during which the diatom divides into two parts, producing two "new" diatoms with identical genes. Each new organism receives one of the two frustules – one larger, the other smaller – possessed by the parent, which is now called the epitheca; and is used to construct a second, smaller frustule, the hypotheca.
