Leuwenhoek - -discovered microbiology, primitive microscope
- Pasteur - -Disproved spontaneous generation w/ swan flasks
- John Snow - -Father of Epidemiology
- Cholera outbreak in London
- Edward Jenner - -Smallpox vaccine
- Franchesco Redi - -Disproved spontaneous generation w/ flies from meat
*Father of Scientific Method*
- Alexander Flemming - -Penicillin
Antibiotics
- Paul Ehrlic - -"magic bullet" - cure with an injection
Start of chemotherapy
- Joseph Lister - -Aseptic surgery with phenol mists
- Robert Koch - -Cultivate bacteria on solid media (agar)
- Ignaz Semmelweis - -Handwashing and sepsis
- Classification of Fungi - -Molds and yeast:
- by sexual spore
- Classification of Algae - -- by pigmentation
storage products
cell wall
- Classification of Protozoa - -Classified by motility
- Classification of Bacteria - -Prokaryotic
cause disease
- Classification of Viruses - -•Genetic material
- incredibly small
- What substances are unable to permeate a cell membrane? - -if it has a
charge
, Ex: Na+ or Cl -
LEAST PERMEABLE
needs special protein channel
- What is another factor affecting membrane permeable substances? - -Size
(water is an exception)
bigger is slower
- Uniport - -1 thing moving in 1 direction
- Antiport - -2 things simultaneously moving in different directions
- group translocation - -changes structure as it moves through the
membrane (changes to different substance)
- 3 forms of active transport - -uniport
antiport
group translocation
- What are glycocalyces in in a bacterial cell? - -sticky sugary substance
outside of the cell
- What are the 2 subcategories of glycocalyces? - -Capsule and Slime layer
- What is a capsule? - -Part of glycocalyx that prevents drying out, resistant
to host defenses
- What is the slime layer? - -part of the glycocalyx that prevents drying out
and attaches (creates biofilms)
- Flagella - -responsible for movement
- Falgella with one tail - -monotrichous
- flagella with 1 tail on each side - -amphitrichous
- flagella on all sides - -peritrichous
- flagella bunch on one end only - -lophotrichous
- Bacteria Cell walls - -protection and structure
