Summary Introduction

To differentiate:

In between the two main types of bacterial envelope structure.

Concept introduction

Bacterial envelope includes cell wall, plasma membrane, and glycocalyx. The plasma membrane is composed of a phospholipid bilayer with the function of regulation of exit and entry of substances in and out of the cytoplasm. The cell wall contains mainly peptidoglycan and maintains the shape of the cell. Glycocalyx is a phospholipid layer that lies outside the cell wall and helps the bacteria to resist the immune reactions in the host body.
