Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
All eukaryotes and prokaryotes are surrounded by a ____
A
cell wall
B
cell membrane
C
cell envelope
D
nucleus
Explanation: 

Detailed explanation-1: -Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes.

Detailed explanation-2: -Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment. This double layer consists largely of specialized lipids called phospholipids.

Detailed explanation-3: -All eukaryotic cells have a surrounding plasma membrane, which is also known as the cell membrane. The plasma membrane is made up by a phospholipid bilayer with embedded proteins that separates the internal contents of the cell from its surrounding environment.

Detailed explanation-4: -All prokaryote and eukaryote cells have plasma membranes. The plasma membrane (also known as the cell membrane) is the outermost cell surface, which separates the cell from the external environment.

Detailed explanation-5: -Both prokaryotic and eukaryotic cells are surrounded by a plasma membrane (cell membrane).
