Gram-positive bacteria peptidoglycan, thick cell wall, teichoic acid, stained blue-black

Gram-negative bacteria peptidoglycan, thin cell wall, stained light red

Common ingredients peptidoglycan

Bacterial L-type

Definition: The cell membrane, also called the cytoplasmic membrane, is located on the inside of the cell wall and tightly surrounds the cytoplasm.

effect

Definition The sol material wrapped in the cell membrane is called cytoplasm or protoplasm. It is composed of water, proteins, lipids, nucleic acids and a small amount of sugars and inorganic salts. It contains many important structures.

Ribosomes

Plasmid is the extrachromosomal genetic material of bacteria. It exists in the cytoplasm and is a closed circular double-stranded DNA. It carries genetic information and controls certain specific genetic traits of bacteria. It can replicate independently.

Cytoplasmic granules are metachromatic granules, most of which are nutrients temporarily stored by bacteria, including polysaccharides, lipids, polyphosphates, etc.
