|
|
Basic characteristics of bacteria: many can swim; no nuclear membrane
|
Prokaryotes; Cell Walls made by Peptidoglycan; reproduce by Binary fission; for energy use inorganic and organic chemicals or photosynthesis
|
|
Basic characteristics of Archaea:
|
consist of Prokaryotic cells; Lack Peptidoglycan; live in exteme environments; Methogens;Exteme Halophiles; love salt; thermophiles; hot springs
|
|
Basic characteristics of Fungi: most typical are molds
|
Eukaryotes; have a distinct nucleus containing the cells DNA; cell walls composed of Chitin; Hyphae; use organic chemicals for energy
|
|
Basic characteristics of Protozoa:
|
unicellular, eukaryotic microbes; have flagella and cilia; ingest organic compounds
|
|
Basic characteristics of Algae:
|
wide variety of shapes; eukaryotes; use photosynthesis for energy; Produce molecular oxygen and organic compounds.
|
|
Characteristics of Virus: inert when living outside a host cell
|
Acellular; consist of DNA OR RNA; core is surrounded by protein coat; replicate in a living host cell; coat may have lipid envelope.
|
|
The three Domains:
|
Bacteria; Archea; Eukarya: Protists, fungi, plants, animals
|
|
Robert Hooke
|
reported that living things were composed of little boxes or cells by looking at cork. He laid the groundwork for the concept of the cell theory. all things made of cells; introduced the term cell
