We will male journals for you to keep notes,
drawings and answers to questions as they
come up on the slide.
Journals will be handed in periodically for
grades. If your gone, get the entry from
someone.
Remember that all living things are classified
for various reasons.
Eubacteria
Archaebacteria
Protists
Fungi
Plants
Animals
Bacteria are divided into two main parts:
a. Archeabacteria
b. Eubacteria
Prokaryote is an organism that lacks a nucleus.
Was thought to be the very first organism on
earth.
Archaebacteria lived in very extreme
conditions since that was what the earth was
like at the time.
Some swamps produce so much methane that if
you drop a match it will start burning.
There is a bacteria in the rumen (stomach) of cattle that will digest
the food and produce methane gas as a by product.
Cow manure will be put
into pits with lids and the
gas is kept and used to
power an engine which
powers a generator.
Archaebacteria- live in very hostlie conditions
and feed off of inorganic nutrients.
Eubacteria- Live off of organic material and
live in more hospitable conditions.
photosynthetic-use sunlight as their energy
chemosynthetic- use chemicals in the environment as
their food.
The three shapes of
bacteria are round or
Cocci, rod shaped or
Bacilus and spiral or
spirilla.
Bacillus Anthracis is a
bacterium that lives in the
soils. When injested in the
lungs or nose it can form
cancer. Many older farmers
got cancer from this when they
farmed in open air tractors.
staphylococcus or
sometimes known as
staph infection.
1. Review the microscope procedures.
2. Obtain the 92 W 0001 slides and observe the
eukaryotes and prokaryotes.
3. In your journal, draw the eukaryotes and
prokaryotes.
Most bacteria reproduce by binary fission.
Some bacteria can reproduce sexually. This is
bad because it can pass on important genetic
material to the next bacteria. Information like
how to resist antibiotics.
Penicillin was discovered by Flemming which
can destroy the cell wall.
U.V. light can kill most bacteria by unraveling
the DNA so it can not reproduce.
Heat can kill bacteria.
Others can be poisons (chlorine) and biological
controls
Aerobic Bacteria- Bacteria that require oxygen
to breath.
Anaerobic- Bacteria that do not require oxygen.
Bacteria will also form endospores. It is a
capsule that will protect the RNA and DNA of
the cell in dry conditions or sometimes cold
and hot.
Nitrogen fixation. Taking unusable forms of
nitrogen and converting it into useable forms.
Recycling of nutrients. Decomposing dead
material and raw materials.
Foods and medicine. Bacteria help produce
foods (yogurt, cheese, etc..) and some bacteria
will destroy other bacteria.
You will pick a bacteria disease to report on.
the rubrics will be a little different than the
virus.
Whooping cough, meningitis, botulism,
cavities, dysentery, plague, syphilis, tetanus,
scarlet fever, yaw, pneumonia, gonorrhea,
salmonella, spinal meningitis, Rcky Mtn.
spotted fever, leprosy, tuberculosis, E-coli, food
poisoning, anthrax, diarrhoea, toxic shock
syndrome, tonsillitis, listeriosis, strep throat.
