|
|
What is the term used to describe microorganisms being everywhere?
|
Ubiquitous
|
|
|
What does the term "Binomial System" mean?
|
This means it is a 2 Name System using the Genus and Species.
|
|
|
Define Decomposers.
|
They breakdown dead things; fungi & bacteria are primarily responsible for this.
e.g. Wood --> Cellulose --> glucose --> energy & carbon dioxide |
|
|
Give Photosynthesis examples as well as the nutrient flow.
|
Algae, cyanobacteria, plants.
CO2 --> light --> glucose -->cellulose |
|
|
Give examples of Mineral Weathering/Soil Formation.
|
Bacteria, fungi, helminths.
|
|
|
Define Symbiotic Relationships.
|
Two organisms living together for the benefit of one or both.
|
|
|
What is bioremediation?
|
This is when microbes are used to detoxify toxic substances (e.g. sewage treatment plant; oil spills).
|
|
|
Define procaryotic cells.
|
Cells which do not have a nucleus (e.g. bacteria).
|
|
|
Define eucaryotic cells.
|
Cell which have a nucleus (e.g. protozoans, fungi, algae, helminths).
|
|
|
What are viruses?
|
Not cells, but infectious particles.
|
|
|
The lifestyles of free-living microbes are what?
|
Those which don't require another organism to survive (e.g. decomposers, predators, grazers).
|
|
|
What are examples of free-living microbes?
|
Decomposers, predators, grazers.
|
|
|
The lifestyles of parasitic microbes are what?
|
Those which live in or on a living host. (e.g. worms, pathogens, viruses).
|
|
|
What is Antonie van Leeuwenhoek know for?
|
Invented the microscope???
- 1st to describe microbes - 1675 - published paper on what he found in water. - 1684 - described what he found in his teeth. |
