CELL STRUCTURE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A flexible double-layered sheet that makes up the cell membrane and forms a barrier between the cell and its surroundings.
A
cell membrane
B
cell wall
C
nuclear membrane
D
lipid bilayer
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. This double layer consists largely of specialized lipids called phospholipids.

Detailed explanation-2: -The core of nearly all cell membranes is a double-layered sheet called a phospholipid bilayer.

Detailed explanation-3: -The lipid bilayer (or phospholipid bilayer) is a thin polar membrane made of two layers of lipid molecules. These membranes are flat sheets that form a continuous barrier around all cells.

Detailed explanation-4: -Cell Membranes made of phospholipid bilayer providing a flexible structure that forms a barrier between the cell and its surroundings.

Detailed explanation-5: -The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
