ch 13 Bacteria, Protists, Fungi Flashcards
(38 cards)
what were Microbial Mats
- earliest forms of life
- layered sheets of prokaryotes
- got energy from oceanic hydrothermal vents
Name the Extremophiles
- Halophiles = loved salty areas
- Thermophiles = loved hot areas
- Methanogens = lived without oxygen and released methane
what do all Prokayotes have in common
- cell membrane
- cytoplasm
- ribosomes
- genetic mat
name the shapes of prokayotes
Cocci = circular
Bacilli = cylinderish
Spirilia = spirals
what are the unique features prokaryotic cells hav
- lack membrane bound organelles
- cell wall
- capsule
-chromosomes in NUCLEOID - flagella
- pili
- plasmids
what is a bacteria’s cell wall made of
peptidoglycan (polsacc)
Gram-Postive Cell Wall
thicker, has more layers of peptidoglycan
Gram-Negative Cell Wall
thinner, fewer layers of peptidoglycan and surrounded by outer membrane
Name Bacterial Diseases
- Plague in Athens
- Plague in Justinian
- Black Death
what was the Antibiotic Crisis
overuse and incorrect use of antibiotics result in bacteria becoming resistant to em
who did MRSA affect
people in more dense areas
- military, prisons
name Bacterial Foodborne Diseases and where it comes from
- ecoli, samanella
- comes from animal waste
name Benefical Bacteria ; Food
- yogurt
- cheese
Bioremediation
using prokaryotes to remove pollutants
- remove chemicals
- remove toxic metals from water
- ex oil spills
Name Beneficial Bacteria for Humans
- hav mutual relationships where bacteria and I both benefit and it does not harm me
- can absorb ions
- Synthesize Vit K
- trains immune system
- maintain large intestine cells
- form protective barrier against pathogens
- on my skin, Antimicrobial compounds prevents infections
are Protists in the same Kingdom as either Animals, Plants or Fungi
None
- in its own Protista
Are Protists unicelluar or multicellular?
both
are Protists Eukaryotes or Prokayotes
Eukaryotes
- hav nucles and organelles
which environments are Protists mostly found
aquatic
Coenocytic
hav more than one nucleus
- single cells
Protist Cell Features
- surrounded by plasma on its outside
- uncellular ones hav flagella and can move
Protists on Humans - Bad
- can cause Malaria; in blood cells
- Trypanosomes; sleeping sickness
Protists on Plants - Bad
-Plasmopara Viticola; causes mildew on leaves
-Phytophthora infestans; black slimes on potatoe
Name Beneficial Protists
- eaten a lot; Seaweed
- Symbiotic Relationships; can provide nutrients thru PHOTOSYNTHESIS
- Decomposers; Saprobes feed off of dead organisms, OoOMycetes GROW on dead organisms
