It seperates teh cell structure fromt eh enviorment. The cell wall is semi-permable. It is found external to the cell membrane. The cell memberane is made up of peptidoglycan (protein & sugar) peptide crossbridges (protein). It needs a specialized die to be reviewed. 2 of 5 Structures all bacteria have - CORRECT ANSWERCellmembrane How many structures do some bacteria have: - CORRECT ANSWER-4 - Capsule, Flagella, Pilli, Spores 1 - Capsule (Glycocalyx) - CORRECT ANSWER-The capsule surrounds the cell wall. Fromed by slime serceted by the cell wall What is the capsule is made of - CORRECT ANSWERPolysaccharides (sugar) The capsule around the baccteria cell will increase its virulence: - CORRECT ANSWER-Ability to harm you
