Balaenoptera musculus

The scientific name for the blue whale.

Pathogen

Infectious bacteria that cause diseases.

Peptidoglycan

Methicillin resistant Staphylococcus aureus (MRSA)

A type of bacteria that is resistant to many antibiotics.

Photoautotrophs

Bacteria that obtain energy from photosynthesis.

Chemoautotrophs

Bacteria that derive energy from inorganic compounds like hydrogen, sulfur, or iron.

Antibiotic Resistance

The ability of bacteria to survive and reproduce despite the presence of antibiotics.

Halophiles

Salt-loving organisms that thrive in high-salinity environments.

Thermophiles

Organisms that live in extreme hot conditions.

Psychrophiles

Organisms that thrive in extremely cold environments.

Aerobic Cellular Respiration

The metabolic process that requires oxygen to produce energy.

Anaerobe

An organism that cannot survive in the presence of oxygen.

Coccus

A type of bacterial shape that is spherical.

Capsule

A protective outer layer found in some bacteria.

Ribosomes

Cell structures that synthesize proteins.

Plasmid
