Microbiology The study of microorganisms
Microscopic, single cell , cluster, Carry out life processes INDEPENDENTLY as SINGLE
chains carry out life processes CELLS
dependently or independently?
What are Viruses? microscopic, non-cellular, RNA or DNA
Bacterial and their processes and their 1. Basic - cellular processes
effects on society, humans, animals,
and the environment 2. Applied - practical problems in agriculture,
health and history

microorganisms? 2. fungi
3. Protozoa
4. Algae
5. Viruses
what are bacteria? SINGLE CELLED ORGANISMS
- - prokaryotic
- - no nucleus
bacteria are prokaryotic, what does they have no membrane bound organelles and no
this mean? true nucleus
,what are the three shapes of bacteria? 1. spherical
2. rod
3. spiral
what is an example of a bacteria (from Klebsiella Pneumoniae
book)? - rod shaped
- causes pneumonia
What are algae single celled microorganisms
Are algae eukaryotic or prokaryotic? Eukaryotic
T/F: algae have membrane bound True
organelles and a nucleus - Algae are eukaryotes
T/F: Algae are photosynthetic? True
Where do algae live? Fresh water and marine environments
T/F: algae cause diseases in humans False
- ALGAE DO NOT CAUSE DISEASES IN HUMANS
What is an example of an algae (from Micrasteria
book) - green algae found in FRESHWATER
,what are Fungi? single celled microorganisms (yeasts)
multicelluslar microorganisms (Molds)
what are single celled fungi called yeasts
what are multicelled fungi called molds
Are fungi prokaryotic or eukaryotic? Eukaryotic
