Which structures are found in all prokaryotic and eukaryotic cells?
A
plasma/cell membrane, cytoplasm, and ribosomes
B
plasma/cell membrane, nucleus, and DNA
C
DNA, ribosomes, and cell wall
D
plasma/cell membrane, cytoplasm, and nucleus
Explanation: 

Detailed explanation-1: -Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment.

Detailed explanation-2: -The cells of all prokaryotes and eukaryotes possess two basic features: a plasma membrane, also called a cell membrane, and cytoplasm.

Detailed explanation-3: -All prokaryotes have plasma membranes, cytoplasm, ribosomes, and DNA that is not membrane-bound. Most have peptidoglycan cell walls and many have polysaccharide capsules.

Detailed explanation-4: -Nucleus is present in all eukaryotic cells which contains all the hereditary information.

Detailed explanation-5: -Prokaryotes are single-celled organisms of the domains Bacteria and Archaea. All prokaryotes have plasma membranes, cytoplasm, ribosomes, a cell wall, DNA, and lack membrane-bound organelles.
