Heterotroph vs Autotroph |
Heterotroph feeds on other organisms Autotroph is a self feeder, uses photosynthesis to gain energy. |
|
|
Taxonomy |
the science of classifying all organisms |
|
|
System of classification |
Kindom Phylum Class Order Family Genus Species |
|
|
six kingdoms |
Eubacteria Archaebacteria Protista Fungi Plantae Animila |
|
|
Pathogens |
disease causing agents (ex: E. coli, pneumonia, strep throat)
|
|
|
Capsule |
an outer layer that provides protection against unfavourable environments (ex: heat, cold, antibiotics viruses)
|
|
|
Cell shapes |
Coccus (round) Bacillus (rod) Spirillium (spiral)
Diplo (two) Staphlo (cluster) Strepto (chain)
|
|
|
Chemotrophs |
produce energy by converting inorganic matter into organic matter. They break down dead stuff. You could have a chemo-heterotroph or chemo-autotroph.
|
|
|
conjugation |
one cell passes a copy of a plasmid to a nearby cell, forming a conjugation bridge.
|
|
|
Transformation |
pick up loose fragment of DNA from surroundings. If it came from a different species it is called a horizontal gene transfer.
|
|
|
Endospores |
a structure that forms around certain bacteria when environmental conditions are not favourable. It protects the bacteria – even in extreme conditions. |
|
|
gene therapy |
drugs or DNA are placed inside the virus' capsid to attack certain cells. This tactic of curing viruses and diseases shows real promise as the first conclusive way to treat certain diseases.
|
|
|
protists |
taxonomy`s ``junk drawer`` |
|
|
Clade |
A taxonomic group that includes a single common ancestor and all its descendants |
|
|
Domain |
the highest taxonomic level; there are three domains of life: Eubacteria, Archaea, and Eukaryotes. |
|
|
Capsid |
a protein coat that surrounds the DNA or RNA within a protein capsule. |
|
|
Viroid |
a very small infectious piece of RNA responsible for some very serious diseases in plants. |
|
|
Endosymbiosis |
a relationship in which a single celled organism lives within the cell(s) of another organism. |
|
|
Lysis |
the rupturing of a cell |
