Cell wall: Protects the cell and also maintains a defined shape for the cell.
Plasma membrane: Semi-permeable membrane that controls the substances moving into and out of the cell. Substances are able to pass through it by either active or passive transport.
Cytoplasm: Contains many enzymes used to catalyze chemical reactions of metabolism and it also contains the DNA in a region called the nucleoid. Ribosomes are also found here.
Pili: Helps bacteria adhere to each other for exchange of genetic material.
Flagella (singular flagellum): It is made of the protein called flagellin. It helps bacteria move around by using a motor protein that spins the flagellum like a propeller.
Ribosomes: The site of protein synthesis. Ribosomes contribute to protein synthesis by translating messenger RNA.
Nucleoid: A region containing naked DNA which stores the hereditary material (genetic information) that controls the cell and will be passed to the daughter cells.
