6 Types of Microorganisms |
Bacteria, Viruses, Fungi, Protozoa, Helminths, Algae |
|
|
Origins Of Microorganisms |
Prokaryotes -(pre nucleus) simple cells, unicellular Eukaryotes - (true nucleus) complex cells Viruses- no cells, optional envelope (outer layer) DNA or RNA |
|
|
Bacteria |
Prokaryotes, peptidoglycan cell walls, binary fission Use organic and inorganic chemicals, or photosynthesis (for energy) |
|
|
Archaea
|
Prokaryotes, live in extreme environments - methanogens - extreme halophiles (love salt) - extreme thermophilies (love heat) |
|
|
Fungi |
Eukaryotes, chitin cell walls, use organic chemical for energy molds and mushrooms are multicellular yeast is unicellular |
|
|
Protozoa |
-Eukaryotes, absorb or ingest organic chemicals, maybe mobile via pseudopods, cilia, flagella |
|
|
Algae |
Eukaryotes, cellulose cell wall, use photosynthesis for energy, produce molecular oxygen and organic compounds |
|
|
Viruses
|
acellular, consist of DNA or RNA, core surrounded by a protein coat, coat maybe enclosed in a lipid envelope, replicate only living in a host cell. |
|
|
multicelular animal parasites |
eukaryotes, muticellular animals, parasitic flatworms and round warms are called helminths, microscopic stages in life cycles |
|
|
Robert Hooke |
living things were composed of little boxes or cells |
