What is pH. pH is a measure of the hydorgen ion concentration of a solution. Solutions with a high concentration of hydrogen ions have a low pH and solutions with a low concentrations of H+ ions have a high pH. This may seem like a confusion way to express these reationships, and it is, until you understand what pH stands for.
Because they depend on sunlight for photosynthesis, diatoms generally live in the upper 200 meters of oceans and bodies of fresh water. Some species of diatoms simply float in the water currents near the surface.Others attach themselves to larger floating objects or to the sea floor.ecause they depend on sunlight for photosynthesis, diatoms generally live in the upper 200 meters of oceans and bodies of fresh water. Some species of diatoms simply float in the water currents near the surface.
Under the right conditions, diatoms can reproduce very rapidly and a population of a small species can double each day. Diatoms normally reproduce by binary fission, where one âmother cellâ splits into two daughter cells. (Eureka 2002) WHERE DO THEY LIVE? Given that diatoms are photosynthetic algae, they are restricted to the euphotic zone during the productive phase of their live cycle. Therefore, they are highly sensitive to any environmental changes such as light availability, temperature, salinity etc. In general, diatoms prefer cold, nutrient rich waters.
