Question

Which of the following best describes the structure of the Gram-negative cell wall?

thin layer of chitin with outer membrane on top

thick peptidoglycan layer with embedded teichoic acids

thick peptidoglycan layer with outer membrane on top

thin layer of peptidoglycan under outer membrane

Which of the following is NOT true?

Prokaryotic cells lack a true nucleus.

Eukaryotic cells divide by binary fission.

Prokaryotic cells lack organelles.

Eukaryotic cells may or may not have a cell wall present.

thin layer of chitin with outer membrane on top

thick peptidoglycan layer with embedded teichoic acids

thick peptidoglycan layer with outer membrane on top

thin layer of peptidoglycan under outer membrane

1) The correct option is thin layer of peptidoglycan under outer membrane.

Gram Negative cell walls have thinner peptidoglycan layers. It consist of one or very few layers of peptidoglycan under outer membrane.

2) The correct option is Eukaryotic cells divide by binary fission.

Eukaryotic cells divide by a process of mitosis. Prokaryotic cells divide by binary fission, which is a type of asexual reproduction.
