Correct sequence of layers of bacterial cell envelope from outside to inside?
Understand the Problem
The question is asking for the correct sequence of layers in a bacterial cell envelope from outside to inside, based on the provided options. The objective is to identify which of the provided sequences accurately reflects this arrangement.
Answer
Glycocalyx → Cell wall → Cell membrane
The correct sequence of layers of a bacterial cell envelope from outside to inside is Glycocalyx → Cell wall → Cell membrane.
Answer for screen readers
The correct sequence of layers of a bacterial cell envelope from outside to inside is Glycocalyx → Cell wall → Cell membrane.
More Information
The bacterial cell envelope is comprised of three main layers: the outermost glycocalyx, which serves as a protective barrier; the cell wall, providing structural support; and the innermost cell membrane, which regulates transport in and out of the cell.
Tips
A common mistake is confusing the positioning of the glycocalyx and cell wall. Remember, the glycocalyx is always the outermost layer.
