microorganisms Flashcards
1
Q
pathogenic microorganisms
A
causing or capable of causing disease
2
Q
commensal microorganisms
A
one species benefits while the other is not harmed or helped in any significant way
3
Q
mutualistic microorganisms
A
ecological interaction between two species where they both benefit
4
Q
uses of microorganisms
A
- chemical recycling (e.g. N2 fixing organisms, cyanobacteria, fungal degradation of waste)
- biotechnology (e.g. dairy products, fermentation of alcohol, enzymes like taq, medicine like antibiotics)
5
Q
prokaryote examples
A
- bacteria
- archaea
6
Q
eukaryote examples
A
- fungi
- algae
- protozoa
7
Q
subcellular (not really organisms) examples
A
- viruses
- viroids
- prions
8
Q
eukaryote basic
A
- an organism with a complex cell or cells.
- genetic material is organised into a membrane-bound nucleus or nuclei.
9
Q
prokaryotes
A
- are organisms without a cell nucleus or any other membrane-bound organelles.
- in most cases unicellular (in rare cases, multicellular).

Q
eukaryote detail
A
- Eukaryotes comprise animals, plants, fungi, protozoa.
- Mostly multicellular—as well as various other groups that are collectively classified as protists.
- In contrast, prokaryotes are organisms, such as bacteria and archaea.
- Eukaryotic cells are generally much larger than prokaryotes:
- a variety of internal membranes and structures organelles
- cytoskeleton composed of microtubules, microfilaments and intermediate filaments (for organisation and shape)
12
Q
prokaryote detail
A
- Prokaryotes thrive almost everywhere, including places too acidic, salty, cold or hot for most other organisms.
- Due to their ability to adapt to diverse habitats, prokaryotes are the most abundant organisms on Earth.
- Prokaryotes are divided into two domains: bacteria and archaea
13
Q
most common prokaryote shapes
A
- coccoid / coccus / cocci (sphericalish)
- bacillus / bacilli (rod shaped)
- spirochete (spiral ish)
14
Q
bacterial taxonomy
A
usually only use genus and species and NO kingdom
- life
- domain
- phylum
- class
- order
- family
- genus
- species
* (some) subspecies - serotypes / serovars - strains
