Remember, there are exceptions to every rule. We are going with
statements that should
begin with "For the most part..." or "As far as we know at this
time..."
rokaryotic cells are similar in their chemical composition and
chemical reactions.
rokaryotic cells lack membrane!enclosed organelles including a
nucleus# while
eukaryotic cells have a membrane!bound nucleus and other
organelles.
eptidoglycan is found in bacterial cell walls but not in archaea
or eukaryotic cell walls.

Below you could see Comparison of Plant Cells and Animal
Cells.
Plant Cell Animal Cell
Cell Wall$ell wall made of cellulose is present in
almost all cells.$ell wall is absent.
Plastidslastids like leucoplasts, chloroplast and
chromoplasts are present.%o plastids found.
Chloroplastslants cells have chloroplasts to prepare their
own food.$hloroplasts completely absent.
Vacuoles $ell sap containing vacuoles are present.&acuoles
are usually absent or one
or more small vacuoles are seen.
Lysosomes 'ysosomes not evident. 'ysosomes occur in
cytoplasm.
Nucleus
(ue to the presence of the vacoule at the
centre of the cell, nucleus may be located at
the edge of the cell.
%ucleus is usually located centrally.
Golgi bodieslant cells have many simpler units of golgi
complex, called dictyosomes.
Animal cells have a single highly
elaborate golgi complex.
