Question

peptidoglycan occurs between the chloroplasts membranes of glaucophytes, the first eukaryote group to branch off following primary endosymbiosis. This is strong evidence that all chloroplasts arose from the engulfment of one cyanobacterium by a larger eukaryotic cell because
select one
a) peptidoglycan is a photosynthetic pigment
b) peptidoglycan occurs in the cell wall of prokaryotes
c) prokaryotes produce peptidoglycan as a toxin against predators
d) eukaryotes produce peptidoglycan during phagocytosis
e) peptidoglycans were obtained by conjugation.

Explanation / Answer

Answer: b peptidoglycan occurs in cell wall of prokaryotes.

Peptidoglycan is a compound of sugar and amino acid and is also called murein. It is major component of prokaryotes cell wall.

Presence of it in chloroplasts membranes strongly signify chloplast as structures similar to prokaryote.
