Answer 1

Characteristic	Bacteria	Archaea	Eukarya
Is a nucleus present	No Bacteria are prokaryotes.Prokaryotes do not have a nucleus.	No Archaea are single celled microorganisms.	Yes Eukaryotes have true nucleus.
Does it contain DNA	Yes Bacteria have primitive DNA which is a single,circular chromosome.	Yes Archaea DNA is not in a nucleus.	Yes In eukaryotes DNA is located in the nucleus.
Are membrane-bound organelles present	No Bacteria are simple cells that's why they don't have membrane bound organelles.	No	Yes Eukaryotes have all membrane bound organelles.
Is the domain primarily unicellular or multicellular	Unicellular organisms	Unicellular organisms	They can be both unicellular and multicellular organisms.
Is there reproduction via meiosis	No They reproduce via mitosis or binary fission	No They reproduce via mitosis or binary fission	Yes They reproduce via meiosis.
Is a plasma membrane present	Yes This membrane made up by a phospholipid bilayer	Yes Most archaea are exhibit a single plasma membrane.	Yes The plamsa membrane is made up by a phospholipid bilayer.
Is there a cell wall in some of the members	Yes	Yes	Some eukaryotic cells have a cell wall.
