Cards

Term
Prokaryotes differ from Eukaryotes
Definition
Unicellularity, Cell size, Chromosomes, Cell division/genetic recombination, Internal compartmentalization, Flagella, Metabolic Diversity
Term
Bacteria Differ from Archaea
Definition
Plasma membranes, Cell Wall, DNA replication, Gene expression
Term
S layer
Definition

in some prokarya, there's an additional protein or glycoprotein layer

 

often involve ADHESION

Term
Capsule
Definition
in bacteria often surrounds other wall layers; enables ADHESION and CAUSES disease sometimes
Term
Endospore Formation
Definition

thick wall around genome and small portion of cytoplasm 

highly resistant to environmental stress

Term
Interior of prokaryotic cells are highly organized
Definition
Internal membranes, Nucleoid Region, Ribosomes (smaler)
Term
Generalized vs. Specialized Transduction
Definition

Generalized: any gene can be transferred (lytic)

Specialized: only a few genes can be transferred (lysogenic)

Term
Bacteria in Carbon Fixation
Definition
contribute to the production of oxygen
Term

Bacteria in Nitrogen Cycle

Nitrifying Bacteria

Definition

decomposers return nitrogen to the soil as ammonia and is converted to nitrate

in aquatic bacteria, nitrogen fixation is carried out largely by cyanobacteria
