What are the two groups of bacteria based on differences in their cell envelopes?
Gram-positive and Gram-negative
Aerobic and anaerobic
Spherical and rod-shaped
Pathogenic and non-pathogenic
Solution
Bacteria can be classified into two groups based on the differences in their cell envelopes and the manner in which they respond to the staining procedure developed by Gram. Those that take up the gram stain are called Gram-positive bacteria, while those that do not are called Gram-negative bacteria.
