3 main shapes of prokaryotic organisms |
Cocci, bacilli, spirilla |
|
|
What is thr most important aspect of prokaryotes morphology? |
Size, small cells allow for rapid exchange of wastes and nutrients across the cell membrane promoting high metabolic and growth rates |
|
|
What are some methods of mobility used by prokaryotes? |
Some glide across solid surfaces, some use has vesicles to move in water, but most use flagella |
|
|
How do prokaryotes reproduce? |
Most reproduce by binary fussion, some by sexual reproduction with use of a pilli |
|
|
What environmental factors affect prokaryote growth rate? |
Temperature, pH, water availability, oxygen levels |
|
|
Naming system |
Kingdom, phylum, class, order, family, genus, species |
|
|
Convergent evolution |
Development of similar adaptations by organisms that are unrelated |
|
|
Divergent evolution |
Development of different adaptations by organisms that were once related |
|
|
Ancestral characteristics |
Characteristics that are unchanged after evolution |
|
|
Derived characteristics |
Characterists that have evolved more recently |
|
|
Conservative characteristics |
Traits that morph or change slowly |
|
|
Homologous characteristics |
Characteristics that have the same genetic background but are used for a different function ex. Human arm and bat wing |
|
|
Analogous characteristics |
Characteristics that have different genetic background but are used for the same function |
