|
Prokaryotes |
Simple/ Single Celled Organism..Primitive..No Nucleus |
*Bacteria |
|
|
Eukaryotes |
“Advanced” True Nucleus organized w/Organelles |
Algae, fungi, humans, Protozoa 3 basic shapes of bacteris |
|
|
3 basic shapes of bacteria |
Cocci / Bacilli/ Spirilla |
|
|
|
Capsule / Biofilm |
Outer most layer / Not all bacteria have Has two forms: Slippery- helps WBCs escape..has hard time getting rid of virus Sticky- used for attachment so remains on surface (sticks to surface like a tooth) |
|
|
|
Flagella |
Not all bacteria have one / used for movement...moves towards food and from waste |
|
|
|
Pili |
Short hairlike structures that surround cell..used to attach bacteria to surface |
|
|
|
Cell wall |
Protects membrane..Strong and rigid..functions: Shape of bacteria/protection/Gram stain/ may cause disease |
|
|
|
Cell Membrane |
Fragile and flexible / controls what goes in and out / encloses contents of cell |
|
|
|
Cytoplasm |
All contents inside CELL 80% water..jellylike consistency |
|
|
|
Ribosomes |
Protein factory..proteins (made of amino acids) |
|
|
|
Chromosome |
DNA contained in Chromosome..(1 chromosome) 26 pairs = 46 |
|
|
|
Plasmid |
Tiny piece of DNA (antibiotic resistance gene) easily shared w/other bacteria |
|
|
|
Storage Granules |
Food warehouses / draws from storage when low |
|
|
|
Endospore |
Not all cells make endospore / “OPTIONAL” “Survival capsule” Made of few bacteria / can survive 1,000 +yrs / MOST IMPORTANT THING IN DNA |
Can survive high heat / radiation / freezing and dry temps |
|
|
Compare & Contrast Gram Neg and Gram positive |
Gram positive- cell walls consist of many layers of Peptidoglycan & also contain Teichoic acids (retains purple dye) Gram negative- Bacteria have a lipopolysaccharide—Lipoprotein phospholipid outer membrane surrounding a thin Peptidoglycan layer /have NO TEICHOIC ACID..has thin cell wall |
Gram Neg Functions as poison in body acts as endotoxin / PCN interferes w/ Peptidoglycan used to treat G+ and wall can fall apart exposed fragile membrane attacking structure in cell wall |
|
|
Lysozyme |
Has some effect- found in some solutions in body (Tears / Sweat / Saliva) |
|
|
|
Simple Diffusion |
No energy req..FREE |
|
|
|
Active Transport |
Req. energy / Built in cell membrane “Pumps” |
|
|
|
Osmosis |
Process of gradual assimilation of ideas |
|
|
|
Tetanus |
Found in rusty nail / toxins spread through blood / anti toxin- neutralize |
|
|
|
Botulism |
Spores in soil / contaminated food / food poisoning/ produces different neurotoxin- relax can’t use muscles / extremely deadly |
Spores can be killed at very hot temp..Botox |
|
|
Anthrax |
Bacterial disease of sheep/ cattle affecting skin and lungs |
Biological weapon |
|
|
Clostridia Difficile —C-Difficile |
Inflammation of colon/ DISEASE CAUSED BY SPORE FORMER |
Diarrhea / |
|
|
Describe the functions of the endospores, sporulation and germination..Know diseases 4 INTERACTIONS OF A SPORE AND HUMANS |
Tetanus / Botulism / Anthrax / C-Diff |
|
