The hanging drop method allows the organism to live longer because it does not dry out as quickly. The hanging drop method also offers a better view of true motility.
Wet mount slides can dry out faster due to the heat from the microscope. Hanging drop slides stay hydrated for longer because of the petroleum jelly.
Hanging drop technique is better for observing larger microbes and for observing motility whiles the wet mount technique is better for smaller microbes such as bacteria
In hanging drop it is easy to distinguish the motility of bacteria because it does not dries out easily that wet mount
As first step of differentiation is done by hanging drop method then why all the steps after that are not done by this method????
