Correct Answers ✅The three common characteristics that
all cells share are a Plasma Membrane, Cytoplasm, and
Ribosomes
Compare and Contrast Prokaryotes and Eukaryotes on the
following points: Whether or not they contain membrane-
bound organelles - Correct Answers ✅Eukaryotes and
Eukaryotic Cells contain membrane bound organelles, such
as the nucleus, while Prokaryotes and Prokaryotic Cells do not
contain membrane bound organelles
Compare and Contrast Prokaryotes and Eukaryotes on the
following points: Whether they are multicellular, unicellular,
or both - Correct Answers ✅Eukaryotes and Eukaryotic
Cells are often multi-celled organisms while Prokaryotes and
Prokaryotic Cells are always Unicellular (containing one cell)
Compare and contrast prokaryotes and eukaryotes on the
following points: Their size in μM - Correct Answers
✅Eukaryotes and Eukaryotic Cells have cell sizes with
diameters around 10-100 μM while Prokaryotes and
Prokaryotic Cells have cell sizes with diameters around 0.1-
5.0 μM. Prokaryotes and Prokaryotic Cells are significantly
smaller than Eukaryotic Cells.

Compare and contrast prokaryotes and eukaryotes on the
following points: Which domains of life they belong to -
Correct Answers ✅Eukaryotes and Eukaryotic Cells belong
to the Domain Eukarya while Prokaryotes and Prokaryotic
Cells belong to either the Domain Archaea or Domain
Bacteria
Compare and contrast domains Bacteria, Archaea, and
Eukarya on the following points: Whether or not they contain
prokaryotic or eukaryotic organisms - Correct Answers ✅
Compare and contrast domains Bacteria, Archaea, and
Eukarya on the following points: The types of organisms each
contains - Correct Answers ✅All of life can be divided into
three domains, based on the type of cell of the organism:
Bacteria: cells do not contain a nucleus. Archaea: cells do not
contain a nucleus; they have a different cell wall from
bacteria. Eukarya: cells do contain a nucleus.
Compare and contrast domains bacteria, archaea, and
eukarya on the following points: Are they all genetically
related? - Correct Answers ✅The three domains share a
set of features, including an RNA polymerase, ribosomes,
membrane protein insertion systems and a common genetic
code, asserting their common ancestry to the last universal
common ancestor (LUCA).
