Do all prokaryotes have cell wall?
Can you explain the difference between gram-negative and gram-positive bacteria?
The main difference between gram-negative and gram-positive bacteria is the structure of their cell wall. Gram-negative bacteria have a thinner cell wall and an outer membrane, while gram-positive bacteria have a thicker cell wall without an outer membrane. Additionally, the staining process used to differentiate between the two types of bacteria results in gram-negative bacteria appearing pink or red, while gram-positive bacteria appear purple.
