Question

Quizplus · Accepted Answer

Bacteria can be classified based on their shape and Gram staining. Shape is significant for identifying bacteria because it is a fixed characteristic. Gram staining is an essential technique used in microbiology to differentiate bacterial species based on cell wall properties; thus they are the best choice for classifying bacteria. The other choices (colored pigments and size) are not sufficient for a complete bacterial classification.
