Chapter 3 Flashcards
Exam 1
Has NO membrane bound nucleus
Prokaryotic Cell
HAS a membrane bound nucleus
Eukaryotic Cell
Typically 1 micrometer in diameter
Prokaryotic Cell
Typically 10-100 micrometer in diameter
Eukaryotic Cell
Bacteria and Archae are what cell type?
Prokaryotes
Plantae, Fungi, Animalia, and Algae, and Protozoa are what cell type
Eukaryotes
Antibiotics targeting cell walls in bacteria is an example of
Selective Toxicity
T or F Humans do not have cell walls
True
Cell wall component
Peptidoglycan
Gelatinous, sticky substances surrounding the outside of a bacteria cell
Glycocalyses
Types of Glycocalyses
- Capsule 2. Slime Layer
Type of glycocalyses, firmly attached to cell surface and may prevent bacteria from being recognized by host
Capsule
Type of glycocalyses, loosely attached, sticky, allows attachment to surfaces and formation of biofilm
Slime Layer
Part of bacteria cell, long structures that extend off cell wall helps it move through the environment
Flagella
Are flagella in all bacteria
NO
Type of wiggly looking bacteria
Spirochete
Part of bacteria cell, sticky, bristle-like, used to stick to e/o and other things in environment. Important function of biofilm
Fimbriae
Special type of fimbriae
Pili
One or two per bacteria cell that Transfers DNA from one cell to another
Pili
When cells learn how to stay alive after antibiotics and transfer this info to other cells.
Antibiotic Resistance
Types of Bacteria Cell Walls
- Gram Positive 2. Gram Negative
Type of Bacteria Cell Wall, has thick layer of peptidoglycan
Gram Postive
Type of Bacteria Cell Wall, has thin layer of peptidoglycan
Gram Negative
Type of Bacteria Cell Wall, purple when stained
Gram Positive
Type of Bacteria Cell Wall, pink when stained
Gram Negative
Type of Bacteria Cell Wall, bilayer contains LPS (lipopolysaccharide)
Gram Negative
If a bacteria cell dies and this is released, causes fever, vasodilation, inflammation, shock, and blood clotting
LPS (lipopolysaccharide)
If gram-negative bacteria cell dies and this is released, causes fever, vasodilation, inflammation, shock, and blood clotting
LPS (lipopolysaccharide)
