Micropara

used by bacteria to attach to a host cell.

locomotion

used to exchange genetic material during conjugation

Single-celled microorganisms. • Lacks an organized nucleus or any other membranebound organelle.

-consist of prokaryotic cells, but if they have cell walls, the walls lack peptidoglycan

What are the three main groups of archaea?

live in hot sulfurous water, such as hot springs

live in extremely salty environments

produce methane as a waste product from respiration

rod shaped

round shape

Round to oval

gently curved shape to a corkscrew-like spiral

spiral but more flexible

depend on other organism for their food

synthesize their own food(rely on Co2 and other carbon molecules for energy)

obtain nutrients from dead and decaying organic matter

are thread-like, protein appendages that enable bacteria to move.

share nourishment from the host

is exhibited by organisms that feed on a complex matter

– gets nourishment from a host

microorganisms that grown in oxygen free environment.

oxygen is the absolute requirement for their energy-yielding properties

– they are not affected by the presence of oxygen

they only need small amount of oxygen to generate energy

does not entirely rely on the availability of the oxygen in their environment instead they use anaerobic methods to utilize ATP/energy molecules.

they cannot survive in the absence of oxygen

are thin filamentous appendages that extend from the cell, often in the tens or hundreds. They are composed of pilin proteins and are used by the cell to attach to surfaces. They can be particularly important for pathogenic bacteria, which use them to attach to host tissues

bundles of fibrils that arise at the ends of the cell beneath an outer sheath and spiral around the cell or specifically the

single long circular double stranded DNA molecule devoid of highly conserved histone protein
