CO2, HCO3- for PS, CO3= for Coccolithophorid shells but not CO or CH4 (used by some special types of bacteria) What are the forms of inorganic Nitrogen that Phytos use for growth metabolism? NH3 (NH4+), NO3, NO2 by all kinds of phytos N2 only by cyanobacteria (heterocycsts) What are the forms of inorganic Phosphorous that Phytos use for growth metabolism? PO4 What are the forms of inorganic Sulfur that Phytos use for growth metabolism? SO4 but not S, H2S (used by some special types of bacteria) What are the forms of inorganic Silicon that Diatoms only use for growth metabolism? Si(OH)4 Most bacteria, many protists & all phytos except diatoms grow by first enlarging in size & then divide roughly in half by binary fission (e.g. mitosis). Daughter cells are the same size. The smallest sized cells in the population tend to be cells just recently divided and/or prior to any enlargement by growth. Size variation for a single specie means growth. Diatom Growth:
