Clusters: Staphylo
§
Chains:
Strepto
SHAPES

Come
in a variety of shapes
§
Spiral
§

§
Rod Shaped
BACTERIA:
Pilli:
Hollow
hair like structures made of protein
Allows
other bacteria to attach to other cells
Ribosomes:
Where
proteins are made
Chromosome:
Capsule:
Keeps
the cell from drying out and helps it stick to food or other cells
Cell
Wall:
Thick
outer covering that maintains the overall shape of the bacterial cell
Plasma
Membrane:
Flagella:
A
whip like tail that some bacteria have for locomotion (to help move) to move
towards materials they need to survive. Flagella are made of filaments.
Plasmid
REPRODUCTION of
Bacteria:
1.
Binary Fission:
· Division of a cell into two
genetically identical cells (copies & makes another cell exactly like it)
· One organisms dividing into
two organisms
Fission: Is a type of asexual
reproduction: production of a living thing from only one parent
HOW? The chromosome makes a copy
of itself and divides into two
2.
Conjugation:
· Two prokaryotes attach to each
other and exchange genetic information.
SURVIVAL of Bacteria:
Endospores: The thick-celled structure that forms inside
of the cell.
o
Allow
bacteria to live for many years
o
Survive
through harsh (tough) environments:
§ Boiling/extreme heat
§ Freezing/extreme cold
§ Extremely dry/dehydration
§ A lot of ultra violet
radiation
MUTATION of Bacteria:
Bacteria
reproduce (copy/make more) quickly and their population grows rapidly (fast).
Þ Mutations lead to:
o
New
kinds of genes
o
New
gene combinations (mixes)
o
Genetic
diversity
ECOLOGY of Bacteria: Nutrient cycling and nitrogen fixation
Ø Bacteria are decomposers:
Return important nutrients to the environment. Get food from breaking down dead
matter into simple chemicals.
Ø Nitrogen-fixing bacteria live
in a symbiotic relationship in the root nodules of plants such as
soybeans, clover, and alfalfa.
HELPFUL (good)
Bacteria:
· Normal Flora: Most bacteria that is
harmless (will not hurt you) that live in or on you.
· Decomposers help recycle nutrients into
the soil for other organisms to grow.
· Bacteria grow in the stomach
of cows so it can break down the grass and hay it eats.
Some helpful (good) bacteria
make:
o
Cheese
o
Yogurt
o
Buttermilk
o
Pickles
o
Vitamins
o
Antibiotics
(medicine)
o
Ecoli
on Small Intestine
o
Sour
Cream
o
Insulin
(for diabetes shots)
o
Used
to treat sewage
o
Industrial
Chemicals.
HARMFUL (bad)
Bacteria:
· A small percent of bad
bacteria causes diseases
· Bad bacteria multiply quickly
in an infection
· Bacteria secrete (put out) a
toxin (poison)
· Animals can pass bad diseases
to humans
o
Communicable Disease: a disease is passed from one organism to another
VIRUSES:
· ARE NOT CELLS
· ARE NOT LIVING
· No organelles to take in
nutrients or use energy
· Cannot make proteins
· Cannot move
· Cannot replicate (copy) on
their own
· Can ONLY replicate (copy)
inside a host cell
·
Process or reproduction: LYTIC
CYCLE
· Most viruses range in size
from 5 to 300 nanometers
Basic Structure of VIRUSES
o
Protein
coat
o
Nucleic
acid core (RNA or DNA)
o
Lipoprotein
coat (second coat: only in enveloped viruses)
DNA VIRUSES:
· Are stable
· Do not mutate rapidly (mutate slowly)
· Are single or double stranded
Examples of DNA viruses:
o Smallpox
o Hepatitis B
RNA VIRUSES:
· Are Unstable
· Mutate rapidly (fast)
· Are single or double stranded
Examples of RNA viruses:
o HIV
o Rhinovirus
REPLICATION of Viruses:
The LYTIC CYCLE: The host cell makes copies of the Viral RNA or DNA.
§ Virus attaches to host cell’s membrane and injects its
nuclei acid into the hose cell
§ The viral nucleic acid takes over protein synthesis,
CREATING NEW VIRUS.
§ The host cell BURSTS, LYSES, and RELEASES the new made
virus.
The LYSOGENIC CYCLE:
§ Viral DNA inserts into a chromosome in a host cell.
§ The Infected cell will have the viral genes
permanently.
RETROVIRUSES:
Viruses that have RNA instead
of DNA for their genetic material
Retroviruses have a special
protein capsid
Lipid envelope is obtained
from the plasma membrane of a host cell.
PRIONS:
Proteinaceous Infectious
Particle/Prion:
§ Protein that can cause infectious disease
§ Live in Cells
§ Associated with diseases known as transmissible
spongiform encephalopathies
