Microbiology Flashcards
1
Q
some microbes are
A
- Bacteria
- Viruses
- Fungi
- Protozoa
- Algae
- Prions
- Helminths
2
Q
Bacterial Cells are
A
prokaryotic cells :
- no membrane bound nucleus
- no membrane bound organelles
- have cell wall
3
Q
Bacteria Capsule
A
- slime layer that helps it stick to host and protects it from antibiotics and being engulfed by white cells and prevents it from drying out.
4
Q
Bacteria cell wall
A
- maintains the shape and protects it from bursting
5
Q
Bacteria Cell membrane
A
- performs some function done by organelles in human cells (eukaryotes)
6
Q
Bacteria ribosomes
A
- smaller than eukaryotes some antibiotics can disrupt protein synthesis
7
Q
Bacteria chromosome
A
- larger and circular, contains genetic material to control the cell
8
Q
Bacteria Flagellum
A
- creates a propeller like movement to help the cell reach for food
9
Q
Bacteria timbre
A
- tiny hair-like structure to stick to host
10
Q
bacteria Pili
A
used to transfer genetic material between other bacteria
11
Q
Gram negative bacteria
A
provides barrier to ABs
12
Q
Gram Positive bacteria
A
thick and covers the cell membrane
13
Q
Biofilms
A
co-ordinated functional communities of microbes in a matrix of polysaccharides and hydrogel and attach to a surface such as teeth and provides access to nutrients
14
Q
How do microbes grow
A
binary vision (cell splits into 2)
15
Q
Lag phase Prodromal period
A
when bacteria produces enzymes etc for growth, slow multiplication
