Bio Bacteria Review
Autotroph- Organisms that get their carbon directly from CO2
Pathology- Scientific study of disease
Pilus- protein structures on the surface of some bacteria
Halophile- Salt loving Achaea that live in environments with very high salt concentration
Prokaryote- single celled organisms, lack membrane bound nucleus
Zoonosis- A disease that can be passed down from animals to humans
Endospore- When Gram positive bacteria can form a thick coated, resistant structure
Compare and contrast Gram positive and Gram negative bacteria.
Gram negative- Dyes red its more complicated and has less peptidoglycan
Gram positive- Dyes purple its less complicated and has more peptidoglycan
Compare and contrast Domain Bacteria and Domain Archaea
Bacteria
1. Cell wall contains peptidoglycan.
2. Heterotroph.
3. One kind of RNA.
4. Cannot live in environments with temperatures above 100 degrees Celcius.
Archaea
1.Cell wall lacks peptidoglycan
2. Autotroph
3. Several kinds of RNA
4. Can live in extreme environmental conditions
Know the shapes and structures of bacteria
Bacillus (rod-shaped)
Coccus (round-shaped)
Spirillum (spiral-shaped)
Streptococci (cocci chain)
Staphylococci (cocci cluster)
Groups of Bacteria
Proteobacteria- Symbiotic Bacteria converts nitrogen to ammonia for plants to use, can cause ulcers
Gram Positive- Can cause strep throat, Lactic acid bacteria, used to make antibiotics
Cyanobacteria- work like plants use photosynthesis to get energy from sunlight, give off oxygen
Spirochetes- Gram negative, spiral shaped bacteria they can cause STI
Chlamydia- Gram negative, live inside animal cells
Structure and Function of Bacteria
Cell wall- Protects the cell and gives the cell shape Cell membrane- Regulates what enters and exits the cell
Cytoplasm- Contains the DNA, ribosomes, organic compound
DNA- is a singular, circular strand, no nucleus
Pilli- Helps cells attach to other cells
Endospores- contains DNA, survives during harsh
