Archaea
Eukarya
Bacteria
-
Single-celled organisms
-
No nucleus/organelles inside their body
-
Binary fission (asexual)
-
Extremophyles
-
1977: became it's own domain, separate from prokaryotes due to DNA findings
-
Few thing's are known about the domain as it was only discovered failry recently
-
Look very similar to prokaryotic cells
-
Contain very similar functions to eukaryotic cells (biochemistry)
-
Single-celled organisms
-
Only some micrometers in length
-
Binary fission (asexual)
-
Cell wall ususally contains peptidoglycan
-
Lives in diverse environments
-
Cause for many diseases in humans but also help with health
-
Some are autotrophic, some are heterotrophic
-
Many are decomposers: basically recycle other dead organisms in oder to give nutrition to organisms such as plants
-
Single/multiple celled organisms
-
Membrane-bound structures: primarily nucleus, mitochondria, chloroplasts
-
More complex and larger organisms are eukaryotic
-
Has seven kingdoms
-
Meiois and/or mitosis
-
Unicellular, colonial or mutlicellular
