Question

The following are unifying properties of all prokaryotic and eukaryotic cells, except?
a. ribosomes
b. cell wall with attached plasma membrane
c. dna has genetic material
d. use of all 4 categories of biomolecules.
e. cytoplasm

Answer 1

The unifying properties of both prokaryotic and eukaryotic organisms includes

· Ribosomes

· Cell wall with attached plasma membrane

· DNA has genetic material and

· Cytoplasm

Ribosomes is the organelles where protein synthesis mechanism takes place.

The cell wall with attached plasma membrane contains a phospholipid bilayer along with the proteins which separates the cell from the external environment.

In prokaryotes the DNA present in non-membrane bound nucleoid region whereas in eukaryotes it is present in membrane bound nucleus.

The other materials of the cell within the plasma membrane are known as cytoplasm except nucleus.

Hence the answer for the above question is (d) - use of all 4 categories of biomolecules.

Explanation: The main organic compound present in prokaryotic cells includes macronutrients (Carbon, hydrogen, oxygen, nitrogen, phosphorous and sulphur) that are helpful in making biomolecules includes proteins and nucleic acid. To perform electron transport chain reaction small quantities of nutrients are needed hence it is known is micronutrients.

Whereas Eukaryotes consists of major types of biomolecule which includes carbohydrate, lipid, nucleic acids and proteins.
