Question

Quizplus · Accepted Answer

The first step in identifying a prokaryotic cell type is typically to perform a Gram stain. This is a differential staining technique that can differentiate between two major groups of bacteria based on differences in their cell walls: Gram-positive and Gram-negative. Once the cell type has been identified as either Gram-positive or Gram-negative, additional tests can be performed to further classify or identify the organism.
