Study Notes
- Bacteria
- Archaea
Major Groups of Bacteria
- Archaea is single-celled, lacks a nucleus, and thrives in extreme conditions.
- Bacteria is single-celled, lacks a nucleus, and only lives in normal conditions.
X-TREME Bacteria
- Archaea can live in geysers, Antarctica, deep-sea ocean vents, and acidic places, possibly beyond Earth one day.
Shapes of Bacteria
- Bacteria shapes can be determined based on their name
- Staphlo- groups grow in clusters.
- Strepto- groups grow in chains.
- Coccus refers to the shape being spherical shaped.
- Bacillus refers to the shape being rod shaped.
- Spiral is another shape of bacteria.
MOVEMENT!
- Bacteria movement occurs because of flagella.
- A-Monotrichous
- B-Lophotrichous
- C-Amphitrichous
- D-Peritrichous
Good Sides of Bacteria
- Bacteria can ferment foods, such as sauerkraut and cheese.
- Bacteria can clean up the environment by being decomposers.
- Decomposers are bacteria and fungi, they feed on dead things and break them down into minerals which living things can use.
- Bacteria can help develop antibiotics and produce insulin.
- Bacteria can help digest food and provide essential vitamins.
Bad Sides of Bacteria
- Bacteria can cause disease, food or water spoilage, and body odor.
Superbugs
- When bacteria become resistant to certain antibiotics, they become more harmful.
MRSA
- MRSA stands for Methylicillin Resistant Staphlococcus areus.
How to make a Super Bug
- Superbugs can be created if people don't finish their antibiotics, which allows the bacteria to develop resistance.
- Bacteria can mutate, which entails changing its DNA, making it resistant to antibiotics.
Spoilage
- Bad bacteria can grow uncontrollably and spoil food.
- Spoilage can be delayed by refrigeration (cooling below 42 degrees), salting, smoking/drying out the food, freezing, and boiling/canning, which kills bacteria and keeps Oâ‚‚ out.
Bacteria Reproduction
- Binary Fission is how bacteria reproduce, they duplicate their DNA and split.
- This is asexual, meaning that it only takes one bacteria to reproduce.
Bacterial Infections
- Typhoid Fever
- Leprosy
- Tetanus
- MRSA (methilicillin resistant Staphalococcus aureus)
- Meningitis
- Ulcers
- Bubonic Plague (possibly)
- Tuberculosis
- Botulism
