a
a cell membrane made of a lipid bilayer
b
a nucleus that contains DNA
c

d
mitochondria that contain DNA
1 answer
The correct answer is:
a. a cell membrane made of a lipid bilayer
All cells, whether prokaryotic or eukaryotic, have a cell membrane that is composed of a lipid bilayer. Prokaryotic cells lack other internal structures such as a nucleus, cell wall made of cellulose, or mitochondria, which are found in eukaryotic cells.
