A tightly bound accumulation of gelatinous material surrounding the cell wall.

Enhances bacterial virulence by preventing phagocytosis and allows adherence to surfaces.

A layer external to the cell wall of Gram-negative bacteria, made of phospholipids, proteins, lipoproteins, and lipopolysaccharide

Acts as a protective barrier, hindering entry of harmful substances (like bile, antibiotics).

The space between the plasma membrane and cell wall, only in Gram-negative bacteria

Region containing the single, circular chromosome (ccDNA) of bacteria.

Small, circular DNA fragments, separate from the chromosome, with genes for extra functions (e.g., antibiotic resistance

Enzymes secreted by bacteria to break down large molecules outside the cell.

A cell lacking a membrane-bound nucleus and organelles; its cell wall is usually peptidoglycan. It reproduces via binary fission.

A cell with a membrane-bound nucleus and organelles. Its cell wall (if present) is composed of cellulose or chitin; mitosis is its reproduction method

A spherical-shaped bacterium.

A rod-shaped bacterium.

A spiral-shaped bacterium.

Pairs of cocci (spherical bacteria) after cell division.

Chains of cocci after multiple divisions in a single plane

Clusters of cocci after divisions in multiple planes

Short, hair-like structures on bacterial surfaces. Used for attachment and conjugation (DNA transfer).

Short, hair-like structures that help bacteria attach to surfaces.

Long pili involved in transferring DNA between bacteria.

The three layers (plasma membrane, cell wall, and capsule) surrounding a bacterial cell's protoplasm.

Rigid structure surrounding the plasma membrane, providing shape and protection from bursting.

Thick peptidoglycan layer, composed of many layers.

Thin peptidoglycan layer, with an outer membrane.

Main component of bacterial cell walls, a polymer of sugars linked by amino acids.

Sugar polymers in Gram-positive walls that help maintain shape and cell division.

Region in gram-negative bacteria between the outer membrane and the cytoplasmic membrane, holding proteins involved in transport systems.
