Domain: Eukarya

Organisms made of one or more cells that have nuclei and organelles like mitochondria

They have organelles and nuclei, some are unicellular(protists) and some are multicellular, complex molecular machinery

Prokaryotes

They are unicellular, it’s more complex than bacteria molecular machinery inside

Prokaryote Cells

They do not have nuclei or organelle compartments, unicellular, simple molecular machinery inside

Last Universal Common Ancestor(LUCA)

Populations of organisms that were ancestors to all current day organisms. (May not have been the first organism).
